After we moved our RT from a dedicated server to a VM and also upgraded our Debian OS we had some trouble with apache eating up all the memory. I decided to install Munin to monitor the server and to see if the performance tweaks take effect.
I also wanted to monitor the RT ticket load time, but there wasn’t any plugin. So I’ve created one: rt_ticket_loadtime
Today we moved one of our RT from a 4 years old Fujitsu-Siemens RX300 S3 with 2x Intel(R) Xeon(TM) CPU 3.20GHz and 2GB RAM to our VMware ESX Cluster. The VM is configured with 4 CPU and 4GB RAM. With this move we also upgraded the OS from Debian lenny to squeeze. The actual copy job of our 4GB DB took 30 minutes.
I took this opportunity to move our customizations from the local folder into an RT Extension.
Today I completed my second exam for the LPIC-1 (Linux Server Professional) Certification.
