F5 Log monitoring

We are having LTM,ASM and APM modules in our F5 device. I need to check and monitor the logs on daily basis. Please help me with commands and procedures to check the logs every day.

    Unix command 

    tail -f
    or 
    tailf
    will print out the last 10 lines of a file and then wait for the file to grow.

    You can try other unix command to check log file

    cat /var/log/ltm | more  --> It will return page wise log file & press spacebar
more /var/log/ltm

    If you wanted to see older log(i.e previous day) file then 

    zcat /var/log/ltm.1.gz | more

    Remote log management is always best option to monitor log.

Hi Manik

 

tailf /var/log/ for instance tailf /var/log/ltm. this requires you to be ssh(ed) into the box on a daily basis. Alternatively you can setup remote logging, this should be best as you require daily basis analysis.

HTH eben.
