NimbostratusThere was some issue on application where backend node were flapping so I want to check the back logs for that pool to share with them.
Please help me with the F5 CLI command to check the old logs of backend node status on F5.
MVPHow old is the incident. Depending upon the logs that has been flowing in the respective F5, the logs get rotated/archived.
Try the 1st command to see how old files you could see.
The second cmd checks the ip 1.1.1.1 (it could be assumed as node ip Or any ip as a matter of fact) in the uncompressed ltm files.
The last cmd checks on the archived files.
ls -ltrh /var/log/ltm*
cat /var/log/ltm* | grep 1.1.1.1
zcat /var/log/ltm* | grep 1.1.1.1
If you get zero hits, presumably the logs are rotated.
