本文介绍了CSSDAGENT和CSSDMONITOR两个进程的关键作用。这两个进程均由OHASD启动，负责监控节点挂起、OCSSD进程挂起及第三方集群软件的状态。它们均为多线程、高优先级，并以root用户身份运行。

CSSDAGENT - This process is spawned by OHASD and is responsible for spawning the OCSSD process, monitoring for node hangs (via oprocd functionality), and monitoring to the OCSSD process for hangs (via oclsomon functionality), and monitoring vendor clusterware (via vmon functionality). This is a multi-threaded process that runs at an elevated priority and runs as the root user.

Startup sequence: INIT --> init.ohasd --> ohasd --> ohasd.bin --> cssdagent

CSSDMONITOR - This proccess also monitors for node hangs (via oprocd functionality), monitors the OCSSD process for hangs (via oclsomon functionality), and monitors vendor clusterware (via vmon functionality). This is a multi-threaded process that runs at an elevated priority and runs as the root user.
