  • As such there is no documentation available but you can follow few recommendations .

    *  Always check cpu, memory, process, orphans object etc.and take actions.

    * Clear the unwanted file i.e ucs, qkview, asmqkview, .pcap etc. from /var/tmp or wherever you kept it.

     *  Remove asm audit/history file which is no used.

    * Failover active node every Months or alternate months.

    *  Update signature(ASM), firmware if require. 

    * add if anything missed.



  • Yes, there are several important items you should include in your preventive maintenance  checklist for F5 LTM devices. Here are some suggestions:

    Check for software updates: Ensure that the F5 LTM device is running on the latest software version, and install any necessary patches or updates.

    Verify system logs: Check the system logs for any unusual events or errors that could indicate a problem with the device.

    Check disk space: Monitor the available disk space on the device, and take action if it is running low.

    Verify SSL/TLS certificates: Check the SSL/TLS certificates installed on the device, and renew or replace any that are expiring soon.

    Test network connectivity: Test the network connectivity between the F5 LTM device and other devices on the network to ensure that traffic is flowing smoothly.

    Verify hardware health: Check the hardware health of the device, including the power supply, fans, and temperature sensors.

    Review security policies: Review the security policies configured on the F5 LTM device, and update them as necessary to ensure that they are providing adequate protection
