OP5 - Duplicate Notifications

Problem:

There are cases that contacts are getting duplicate notifications whether through SMS or Email.

Probable cause:

Oftentimes this is due to misconfiguration of /opt/monitor/op5/merlin/merlin.conf file either from the Master or/and Poller nodes. 

Solution:

Given that notifications will be configured from the Master.

From the Master's merlin.conffile, find the configuration block related to the Poller and insert the option notifies = no at the end of the block.

Example:

poller A {
port = 15551
address = A
hostgroup = X_prod,X_reserv,X_test
takeover = no
notifies = no
}

After saving the changes, run mon restart.

From the Poller'smerlin.conffile, look for module configuration block and insert the option notifies = no at the end of the block.

Example:

# module-specific configuration options.
module {
# textual log of normal hum-drum events
log_file = /var/log/op5/merlin/neb.log;
notifies = no
}

After saving the changes, run mon restart.
