The parameters below are managed in Nagios but not in Shinken because they are useless in the architecture. Nagios event_broker_options you really need nagios event_broker_options of them, please use Nagios instead or send us a patch: The title is quite ambiguous: By setting this value to -1Nagios will check for external commands as often as possible.
Each time Nagios checks for external commands it will read and process nagios event_broker_options commands present in the External Command File before continuing on with its other duties. More information on external commands can be found here. This option determines how many buffer slots Nagios will reserve for caching external commands that have been read from the external command file by nagios event_broker_options worker thread, but have not yet been processed by the main thread of the Nagios nagios event_broker_options.
Each slot can hold one external command, so this option essentially determines how many commands can be buffered. For installations where you process a large number of passive nagios event_broker_options e. This setting determines whether or not Nagios will set various program-wide state nagios event_broker_options based on the values saved in the retention file.
If nagios event_broker_options do not have State Retention Option enabled, this option has no effect. This setting determines whether or not Nagios will retain scheduling info next check times for hosts nagios event_broker_options services when it restarts.
If you are adding a large number or percentage of hosts and services, I would recommend disabling this option when you first restart Nagios, as it can adversely skew nagios event_broker_options spread of initial checks. Otherwise you will probably want to leave it enabled. This is an advanced feature. These options determine which host or service attributes are NOT retained across program restarts. Nagios event_broker_options default, all host and service attributes are retained.
These options determine which process attributes are NOT retained across program restarts. There are two masks because there nagios event_broker_options often separate host and service process attributes that can be changed.
For example, host checks can be disabled at the nagios event_broker_options level, while service checks are still enabled. By default, all process attributes are retained. These options determine which contact attributes are NOT retained across program restarts.
There are two masks because there are often separate host and service contact attributes that can be changed. Using no delay is generally not recommended, as it will cause all service checks to be scheduled for execution at the same time. This means that you will generally have large CPU spikes when the nagios event_broker_options are all executed in parallel.
More information on how to estimate how the inter-check delay affects service check scheduling can be found here. Values are as follows:. This is the number of seconds that Nagios will sleep before checking to see if the next service or host check in nagios event_broker_options scheduling queue should be executed.
This variable determines how service checks are interleaved. Interleaving allows for a more even distribution of service checks, reduced load on remote hosts, and faster overall detection of host problems. Setting this value to 1 is equivalent to not interleaving the service checks this nagios event_broker_options how versions of Nagios previous to nagios event_broker_options. Set this value to s smart for automatic calculation of the interleave factor unless you have a specific reason to change it.
The best way to understand how interleaving works is to watch the status CGI detailed view when Nagios is just starting. You should see that the service check results are spread out as they begin to appear. More information on how interleaving works can be found here. This option allows you to specify the maximum number of service checks that can nagios event_broker_options run in parallel nagios event_broker_options any given time.
Specifying a value of 1 for nagios event_broker_options variable essentially prevents any service checks from being run in parallel.
Specifying a value of 0 the default does not place any restrictions on the number of concurrent checks. More information on how to estimate how many nagios event_broker_options checks you should allow can be found here. These nagios event_broker_options consitute the core of the monitoring logic in Nagios.
If there are a lot of results to process, reaper events may nagios event_broker_options a long time to finish, which might delay timely execution of new host and service checks. This variable allows you to limit the amount of time that an individual reaper event will run before it hands control back over to Nagios for other portions of the monitoring logic. This options determines which directory Nagios will use to temporarily store host and nagios event_broker_options check results before they are processed.
This directory should not be used to store any other files, as Nagios will periodically clean this directory of old file see the: Max Check Result File Age option above for more information. Make sure that only a single instance of Nagios nagios event_broker_options access to the check result path. If multiple instances of Nagios have their check result path set to the same directory, you will run nagios event_broker_options problems with check results being processed incorrectly by the wrong instance of Nagios!
Check result files that are older that this threshold nagios event_broker_options be deleted by Nagios and the check results they contain will not be processed. Using no delay is generally not recommended. Using no delay will cause all host checks to be scheduled for execution at the same time. More information on nagios event_broker_options to estimate how the inter-check delay affects host check scheduling can be found here.
This can help to balance the load on nagios event_broker_options monitoring server, as it will attempt to keep the time between consecutive checks consistent, at the expense of executing checks on a more rigid schedule. This option determines how often in seconds Nagios will attempt to automatically reschedule checks. This option nagios event_broker_options has an nagios event_broker_options if the Auto-Rescheduling Option option is enabled.
Default is 30 seconds. Only nagios event_broker_options and service checks that occur in the next X seconds determined by this variable will be rescheduled.
Default is seconds 3 minutes. Nagios tries to be smart about how and when it checks the status of hosts. In general, disabling this option will allow Nagios to make some smarter decisions and check hosts a bit faster.
Enabling this option will increase the amount of time required to check hosts, but may improve reliability a bit. Unless you have problems with Nagios not recognizing that a host recovered, I would suggest not enabling this option. This can be very useful in distributed and failover monitoring installations. More information on passive check state translation can be found here.
This option determines whether or not Nagios will free memory in child processes when they are fork ed off from the main process. By default, Nagios frees memory. By defining this option in your configuration file, you are able to override things to get the behavior you want. This option determines whether or not Nagios will fork child processes twice when nagios event_broker_options executes host and service checks.
By default, Nagios nagios event_broker_options s twice. Nagios event_broker_options option controls what if any data gets sent to the event broker and, in turn, to any loaded event broker modules.
This is an advanced option. When in doubt, either broker nothing if not using event broker modules or broker everything if using event broker modules. Possible values are shown below. This directive is used to specify an event broker module that should by loaded by Nagios at startup. Use multiple directives if you want to load more than one module. Arguments that should be passed to the module at nagios event_broker_options are seperated from the module path by a space.
This option determines where Nagios should write nagios event_broker_options information. What if any information is written is determined by the Debug Level and Debug Verbosity nagios event_broker_options. You can have Nagios automaticaly rotate the debug file when it reaches a certain size by using the Maximum Debug File Size option.
This option determines what type of information Nagios should write to the Debug File. This value is a logical OR of the nagios event_broker_options below.
This option determines how much debugging information Nagios should write to the Debug File. This option determines the maximum size in bytes nagios event_broker_options the debug file. If the file grows nagios event_broker_options than this size, it will be renamed with a.
If a file already exists with a. Note The title is quite ambiguous: Values are as follows: An interleave factor of 1 is equivalent to not interleaving the service checks. Shutdown Nagios, replace the module file, restart Nagios While Nagios is running Read the Docs v:
In the case that you have followed steps mentioned nagios event_broker_options installation of the Nagios Core document at this web page it is located at: Nagios Core is using several configuration files that have direct or indirect definition of nagios event_broker_options relation to each other.
In this document I would like to describe the functionality of the main configuration files used at Nagios Core. On another hand I think that it is pointless nagios event_broker_options copy the whole official documentation from Nagios project in to tis document. According to this Nagios event_broker_options will nagios event_broker_options to find the balance between information that can help to understand how it is working and pointing to official documentation.
Mentioned configuration file will be used at start of Nagios event_broker_options Core demon. It is including the configuration of Nagios Core, nagios event_broker_options well it is possible to define additional files that can provide particular configuration used at Nagios Core. According to this it is common to split the nagios event_broker_options across several files. It is possible to create file system hierarchy that will provide the possibility to logical grouping of the configuration objects.
In case that you will need to do roleback it really hand. In the case that you are looking for way how to logical order the configuration across the file system. This is one nagios event_broker_options the main parameter that will be interesting for you.
In this case each configuration parameter is including nagios event_broker_options one configuration file that will be included in to Nagios Core configuration.
In the case that you are looking for way how to logical order the configuration across the file system without defining each configuration file. This is one of the main parameter that can help you. It is possible to build this hierarchy direct at file system like directory structure. Nagios Core is using nagios event_broker_options default the US format of the nagios event_broker_options. In some cases it is too confusing for the peoples that are using this tool.
According to this it is sometime better to change it to another format. In UX world each process has his owner and owner group. Based on this it is possible nagios event_broker_options restrict access rights nagios event_broker_options some resources at OS level. Nagios Core is using as well definition of User and Group that will be used for running Nagios Core demon.
According to this all files and directories that need to be nagios event_broker_options for Nagios Core demon need to belong to the right user nagios event_broker_options group. In the case that you are building a failover Nagios Core infrastructure.
In the case that you can not reload the configuration from config files. Any way this is not topic of this document. I will describe it at different document. In case that you are nagios event_broker_options to integrate Nagios Core with another tools. That are able to send unsolicited messages to Nagios Core to change the status of monitored object. The design of the Nagios Core is so nice, easy and nagios event_broker_options. It is providing us interface that can be used for passive monitoring, as well for changing of parameters at running Nagios Core.
In general this interface is a named pipe FIFO. According to this we can just write our commands in to mentioned FIFO file like in to any standard nagios event_broker_options.
This is one of the main reason that Nagios Core is used at so many monitoring tools. As it is too easy to do integration of Nagios Core. This is the reason that you do not really need any agent on monitored device, as in the case that you have SSH access to Nagios Core monitoring server you can forward all interesting messaged directly to the Nagios Core from monitored server.
Any way this is not topic of this document, as well it is not really common to use it in this way. Nagios Core is able to integrate additional components. In this way it is possible to integrate Nagios Core with several different tools. In this way the Nagios Core will share operational status with another application. In most case you will not really need to change it. On nagios event_broker_options hand in the case that you would like to play with your Nagios Core web interface here are the configuration parameters.
At each Host or Service nagios event_broker_options configuration it is possible nagios event_broker_options specify who can see the status of the particular object. In case that you are using one administrator account that need to see all configured objects it is possible to enable it at nagios event_broker_options please to see all objects nagios event_broker_options Nagios Core even it was not nagios event_broker_options as a contact for particular object.
This option allows you to specify the default nagios event_broker_options method the statusmap CGI should use for drawing hosts. If you do not use this option, the default is to use user-defined coordinates. Valid options are as follows: This option allows you to specify the refresh rate in seconds of various CGIs status, statusmap, extinfo, and outages. This option allows you to specify the default number of results displayed on the status.
This number can be adjusted from within the UI after the initial page load. Setting this to 0 will show all results. It is possible to define 32 different paths. Table of Contents Nagios Core Configuration - nagios.
In the case that you are going to do any configuration change. In the case that you would like to build a hierarchical structure like: SS I do prefer strict-iso, as it is most universal format. Configure the user and group: To enable passive monitoring it is required to configure this parameters: To enable it you will need nagios event_broker_options configure: Used URL is http: Providing help information that can be called directly from web browser.
In short, traders should be informed and binary options brokers should make sure to get the acceptance of a nagios event_broker_options in written. We at Fair Binary Options will not accept any explanations that the customer said yes over the phone. We think brokers should make sure the bonus is accepted in some sort of written form - as regulator requests in order not to be seen as binary options scam.
Also, turnover rules must be confined to bonus alone and not include deposited money. We want to nagios event_broker_options all traders here that widely accepted practice, after bonus was received, is that all trades that end in the money are counted as bonus profits, while all trades nagios event_broker_options are lost are subtracted from the money deposited by the trader.
