Extending ICE-Linux Monitoring

Collection through a Management Processor

ICE-Linux supports management processors using both iLO and IPMI protocols for gathering sensor

and system event log information. To access a system’s management processor, credentials need to

be configured in SIM. The Environment and System Event Log (SEL) services access the management

processor to gather sensor and SEL information. ICE-Linux automatically configures iLO-equipped

systems to collect this data; however, IPMI-based management processors are not currently discovered

by HP SIM, so a manual step is required to support them.

Collecting Metrics through OS agents

ICE-Linux installs two small management agents on each of the managed systems to collect operating

system metrics; they are the Supermon mond daemon and the Nagios Remote Plugin Executor, nrpe.

The mond daemon is used for all local OS metrics collection. The nrpe plug-in is only used by ICE-

Linux for control operations (reconfiguration requests), not for periodic data collection.

The ICE-Linux agents are built to be generic. These agents can be deployed to any Linux platform.

Any x86-based Linux platform that can run the agents can be monitored by ICE-Linux.

Syslog Collection

ICE-Linux configures syslog or syslog-ng on each host to forward events to a global syslog-ng

log aggregator running on the HP SIM Central Management Server (CMS). The resulting log is saved

on the CMS to the /hptc_cluster/adm/logs/consolidated.log file. This information is

periodically scanned by the Nagios Syslog Alert Monitor plug-in and checked for known patterns as

defined in the syslogAlertRules file. This information is collected without the need for any ICE-

Linux specific agents on Linux platforms.

Procedure for Monitoring Other Linux platforms

The following steps describe the procedure to configure ICE-Linux to monitor any Linux based system

with hardware BMC and IPMI over LAN capability.

These steps are:

Step 1: Discover Systems in HP SIM

Step 2: Establish SSH Keys and Deploy Managem

ent Agents

Step 3: Verify ipmitool Connectivity and Credentials

Step 4: Adding Management Processor Credentials to HP SIM

Step 5: Assign ICE-Linux License to Host

Step 6: Update ICE-Linux Management Services

Step 7: Run the addbmc Utility

Step 8: Resynchronize Management Data

Step 9: Update Menu Option

Step 1: Discover Systems in HP SIM

Use the HP SIM Options Discover menu entry to add the IP address for the target system and the IP

address for its corresponding IPMI port.
