Reactionner Definition


The Reactionner daemon is in charge of notifications and launching event_handlers. There can be more than one Reactionner.

Definition Format

Variables in red are required, while those in black are optional. However, you need to supply at least one optional variable in each definition for it to be of much use.

define reactionner{  
reactionner_name reactionner_name
address dns name of ip address
port port
spare //[0/1]//
realm realm name
manage_sub_realms [0,1]
modules modules

Example Definition:

define reactionner{
    reactionner_name      Main-reactionner
    address               node1.mydomain
    port                  7769
    spare                 0
    realm                 All

    # Optional parameters
    manage_sub_realms     0   ; Does it take jobs from schedulers of sub-Realms?
    min_workers           1   ; Starts with N processes (0 = 1 per CPU)
    max_workers           15  ; No more than N processes (0 = 1 per CPU)
    polling_interval      1   ; Get jobs from schedulers each 1 second
    timeout               3   ; Ping timeout
    data_timeout          120 ; Data send timeout
    max_check_attempts    3   ; If ping fails N or more, then the node is dead
    check_interval        60  ; Ping node every minutes
    reactionner_tags      tag1
    modules               module1,module2

Variable Descriptions

This variable is used to identify the short name of the reactionner which the data is associated with.
This directive is used to define the address from where the main arbier can reach this reactionner. This can be a DNS name or a IP address.
This directive is used to define the TCP port used bu the daemon. The default value is 7772.
This variable is used to define if the reactionner must be managed as a spare one (will take the conf only if a master failed). The default value is 0 (master).
This variable is used to define the realm where the reactionner will be put. If none is selected, it will be assigned to the default one.
This variable is used to define if the poller will take jobs from scheduler from the sub-realms of it’s realm. The default value is 1.
This variable is used to define all modules that the reactionner will load.
This variable is used to define the checks the reactionner can take. If no reactionner_tags is defined, reactionner will take all untagued notifications and event handlers. If at least one tag is defined, it will take only the checks that are also taggued like it.

By default, there is no reactionner_tag, so reactionner can take all untagued notification/event handlers (default).
