The above graph represents the CPU Graph of a server. A server which we’d recently been having performance issues with.
Everything worked, and it did appear that one process seemed to run longer than it used to but we couldn’t for the life of us figure out why.
Today we stepped back and looked at basics. Brought up the logging graphs associated with this box and there it was plain as day.
Something changed towards the end of Week 39.
This information alone pointed to some external changes that we made during that week that software on this box was having trouble coping with.
Without this baseline we’d still be beating our brains in.
In this case Cacti, is being used to monitor and log CPU, disk space, bandwidth, SQL queues and what not. Again, this proves to be well worth having.
