I'm using Sensu to see if error log exists in log files with check-log.rb
.(https://github.com/sensu-plugins/sensu-plugins-logs/blob/master/bin/check-log.rb)
I think we don't need "OK" notification when it comes to checking error log, so I'd like not to notifiy "OK" when checking log files in Sensu. I know how to do it in Nagios, but cannot find the way in Sensu's document.
Does anyone help me with this?
Thank you in advance.
It is quite simple actually. You need to define a filter that removes the OK/resolved messages.
{
"filters": {
"resolve": {
"attributes": {
"check": {
"status": 0
}
},
"negate": true
}
}
}
Then apply the filter on your handler. If you use the default handler you need to define a new handler with the 'default' name.
If you want some more flexibility you can add
{
"filters": {
"resolve": {
"attributes": {
"check": {
"status": 0,
"filter_resolve": true
}
},
"negate": true
}
}
}
You can then add this filter to all your handlers. If you include the custom attribute "filter_resolve": true
to the checks you want to filter resolve events on, it will do so. All other checks will ignore this filter since they do not have the attribute "filter_resolve": true
.
