Splunk UF Deployment - Possible Issues

[johann2017]

Hello. We are planning on deploying UFs across our enterprise ~ 3000 systems. Currently, we have deployed UFs to 50 systems and have seen no issues. Before doing a large deployment to cover our entire enterprise - I was curious if anyone has seen any issues arise from deploying UFs?

The rule of thumb is 1KUFs/1-minute of phone-home with default settings. The default is 1-minutes so 1K servers with default settings before you run into scaling problems.

If you are able to monitor the UF _internal log, you can possibly detect issues. The classic issue is that they maxthruput throttles the UF and the UF will get their data indexed in burtsts. If they roll logs they might miss events.

A single deployment server can easily handle that many UFs. Just remember to set phoneHomeIntervalInSecs to 600 or so (default is 60 seconds) in deploymentclient.conf.

Thanks rich! Have you seen any other issues arise on the network, endpoints, servers or anything else or "gotchas" from mass deploying the UFs?

In general, no. UFs are very straightforward to deploy. Problems are always possible, however, if you exceed the capacity of any of your resources.
