The The UNIMAS monitor was down over the new year. The problem was that the pinger2.pl file was moved. It is now workingwas restored, however it looks like was running an older version, it does not have the individual ping response just the min/avg/max. This is being investigated. Johari has fixed this.
The tool to enable synchronizing Malaysian monitors is completed. It provides the ability to add, edit and delete nodes. However there are still some errors (wild cards) in the pinger.xml file produced. Johari is working on it.

PingER at SLAC
We are working on the annual PingER report for the International Committee on Future Accelerators (ICFA). It is due mid January. We just need to incorporate the high performance monitoring section from Shawn McKee.
