Scheduled Datagroup modification

We use a lot of data-groups associated with external files for our layer 7 VIPs. Currently, we make changes and update to the external files at night, then manually run a script to update the LTM data groups and sync the config. I'm working on removing most of the off hours work by scheduling the script to run automatically at some time in the very early AM without anyone having to be awake enough to make a mistake. That way, the file updates can happen during the day, and the script runs automatically at night.

 

 

I was thinking that adding it as a cron job might be the way to go, but figured I'd run this by the community to see if someone has already done it. I can see a couple of piece of intelligence that I'm going to need to build into the script, ie, only run from the active node in the HA pair, revert to the backup external file on errors, etc, but that's all doable. What I'm looking for is has anyone done this kind of thing before, scheduling a script to run on the LTM at a specific time and any problems/issues that they've run into.

 

 

Thanks for the assistance.
