The check_rhc software uses snmp to monitor and verify the status of a RHES Cluster, providing users with a quick and efficient way to ensure their cluster is functioning correctly.
Check_rhc is a useful software designed to offer users the ability to check the status of a RHES cluster through snmp. The tool requires certain options to be enabled, such as the hostname to query, which is a mandatory field for usage. Additionally, the SNMP read community should be provided to allow the software to function smoothly, with a default option of "public" when not specified.
With snmp version, the software allows users to choose between version one and two, with version two using get_bulk feature for less overhead. Version three is also supported, requiring the user to input the username for SNMPv3 context through the -U option. Other options that users can set include the SNMP port to use, the security level to choose, and the SNMPv3 context name.
Moreover, other parameters that can be specified are authentication and privacy passwords, which can either be clear text ASCII or localized key in HEX with 0x prefix generated by using the "snmpkey" utility. Specify the authentication protocol, which can be either MD5 or SHA1 then set the privacy password to get the desired security level. By setting the maximum message size, the plugin can be configured for v1 or v2c, and users can set a defined time before the plugin times out, which is set as the default for 15 seconds.
After installation, it's essential to Install "cluster-snmp" delivered from Red Hat, then start modclusterd per "service modclusterd start" and add "dlmod RedHatCluster /usr/lib/cluster-snmp/libClusterMonitorSnmp.so" to your snmpd.conf. The user help option is also available, with the software version specified as the plugin version. In conclusion, Check_rhc is an essential tool for RHES cluster monitoring, provided users follow the installation and configuration procedures as outlined.
