Remove spikes in RRD Ganglia graphs

There is a script that does the trick on /opt/cscs/bin/remove_spikes. The script is also attached in this page (see attachments below).

The process is something like this:

• First make a backup of the rrd file cp storage01_free_cms.rrd storage01_free_cms.rrd.backup
• Then dump the RRD data into an XML file: rrdtool dump storage01_free_cms.rrd > storage01_free_cms.rrd.xml
• Change the values you want to change inside the XML to NaN, for example: sed 's/[0-9]\.[0-9]*e.13/NaN/' -i storage01_free_cms.rrd.xml
• And finally dump the data back to the RRD file, it should overwrite the previous values: rrdtool restore -f storage01_free_cms.rrd.xml storage01_free_cms.rrd

ILOM tips and Tricks

We use iloms to access the machines. Here are some helpful hints:

1. Use the itools - istat, ioff, ion, ireset, idisk, etc in /root/bin

2, in order to set up a new ilom from, say supermicro, or IBM:

supermicro - username - ADMIN, password - ADMIN
ibm - username ADMIN, password - PASSW0RD (with a zero, I believe)

next, add user, etc:

ipmitool -I lan -H 192.168.66.79 -U ADMIN user set name 3 root
ipmitool -I lan -H 192.168.66.79 -U ADMIN user set password 3 changeme
ipmitool -I lan -H 192.168.66.79 -U ADMIN user priv 3 4 1
ipmitool -I lan -H 192.168.66.79 -U ADMIN user enable 3
