Just some notes on setting up temperature monitoring and alerting on CentOS/RHEL running on HP ProLiant. The first step is to install lm_sensors:

yum -y install lm_sensors
sensors-detect
sensors

Now we need to install hddtemp package:

yum -y install hddtemp
for i in `fdisk -l 2>/dev/null | egrep -o "/dev/sd[a-z]"` ; do hddtemp $i ; done

Enable HP software delivery repo by following these instructions. The basic process goes something like this:

rpm --import http://downloads.linux.hpe.com/SDR/hpPublicKey1024.pub
rpm --import http://downloads.linux.hpe.com/SDR/hpPublicKey2048.pub
rpm --import http://downloads.linux.hpe.com/SDR/hpPublicKey2048_key1.pub

cat << EOF > /etc/yum.repos.d/mcp.repo
[mcp]
name=Management Component Pack
baseurl=http://downloads.linux.hpe.com/repo/mcp/centos/6.5/x86_64/10.10
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/GPG-KEY-mcp

Make sure to insert the correct flavor, version, arch, and repo rev. Now you can install a couple useful components of HP’s MCP hairball:

yum -y install hp-health hp-snmp-agents hp-ams
chkconfig --list | grep hp
for i in hp-health hp-snmp-agents hp-ams ; do service $i status ; done

To get power supply status, fan speed, and temperature readings:

hplog -p -f -t
