rSeries: config changes in logs

For F5 rSeries load balancers:

 

- Are all configuration changes (e.g. enabling / disabling nodes; creating / modifying / deleting virtual servers) somehow documented in the F5 device's logs?

If yes...

- Where may we find those logs?

- Is there an quick way to somehow convert those logs into CLI commands that we may run in the CLI of other F5 devices?

 

 

Our reason for asking the questions above:

We are currently working on upgrading the F5 load balancers of our customer, from iSeries, to rSeries.

One challenge that we will face is how to completely migrate all of the config from their iSeries to rSeries, noting that they frequently perform configuration changes on their iSeries, practically every day.

  • Any changes made will be held in the /var/log/audit file. The link below is where I would start working out how you are going to see what has changed - while it is not giving the full answer it should provide a good starting point.

    Just be aware that the log files rotate on a daily basis (between 3AM and 4AM as standard) so you might need to check multiple files to get the information you need.
