Presently logfilter only captures the line which matches and puts that in the alert. This requires the support personnel to log into the server to view the rest of the log file which could be huge (several GB). It also introduces challenges in access control.
To simplify log monitoring, you could pull the context of the error message from the logs (~100 lines) via fglam and display via the Foglight web console. This could be provided as a link that pulls the relevant section of logs on-demand.
Enhancement request ID IC-612 created for this issue.
It will be considered for a future release of Foglight.
