o2locktop is a top-like OCFS2 DLM lock monitor
o2locktop is a top-like OCFS2 DLM lock monitor. It displays DLM lock usages via querying OCFS2 file system statistics from the specified nodes. It detects the hot files/directories, whose DLM locks are frequently referenced among the cluster.
Example, the maximal wait time per DLM lock could helps administrators identify which hot files/directories should be decoupled for improving file access performance.
