We use influxdb with nagios and we have a doubt when renaming a host. How to maintain the data history?
Thank you very much

Do you need match the data even when you rename a host?

If it is, you can have a tag to join it, like

host=server1 tag=machine
if you change the name of the host:

host=server2 tag=machine

so, you can use tag=machine to match the information about this server.
Another option could be change by query the name of the host in influx database

Is there an update statement to change the host in influx database?

Thanks!

I think that influxdb doesn’t have this functionality yet, but here you have something it could be useful:
