## 2016-12-28
- We've been getting two alerts per day about CPU usage on the new server from Linode
- These are caused by the batch jobs for Solr etc that run in the early morning hours
- The Linode default is to alert at 90% CPU usage for two hours, but I see the old server was at 150%, so maybe we just need to adjust it
- Speaking of the old server (linode01), I think we can decommission it now
- I checked the S3 logs on the new server (linode18) to make sure the backups have been running and everything looks good
- In other news, I was looking at the Munin graphs for PostgreSQL on the new server and it looks slightly worrying:

- I will have to check later why the size keeps increasing
