check_graylog2_stream is a check script for nagios that verifies graylog2 streams.
The script checks for the last-alarm time of the specified stream and:
-
If the time is within the specified age (sec), a CRITICAL alarm is raised, otherwise OK.
-
By using the inversion option (-i), if the time is within the specified age (sec), an OK status is returned, otherwise a CRITICAL alarm is triggered.
Usage:
./check_graylog2_stream.sh -g <graylog server url> -k <graylog api_key> -t <alarm age> -s <stream name> [-i]
Options:
-i , --INVERT
inverts exit code interpretation (default: OFF)
Examples:
1. INVERT=OFF (default) --> will return CRITICAL if alarm is ON for more than 300 seconds :
./check_graylog2_stream.sh -g http://graylog2.mycorp.com -k da1c06b0e21ffd5cb52bb6e4230fb3439f6b99e8 -t 300 -s My-Stream-Name
2. INVERT=ON (-i) --> will return CRITICAL if alarm is OFF for more than 300 seconds:
./check_graylog2_stream.sh -i -g http://graylog2.mycorp.com -k da1c06b0e21ffd5cb52bb6e4230fb3439f6b99e8 -t 300 -s My-Stream-Name
3. If graylog behind https use -c opt:
./check_graylog2_stream.sh -i -g https://graylog2.mycorp.com -k da1c06b0e21ffd5cb52bb6e4230fb3439f6b99e8 -t 300 -s My-Stream-Name -c
