o2locktop is a top-like OCFS2 DLM lock monitor, it displays DLM lock usages via querying OCFS2 file system statistics from the specified nodes.
You can utilize o2locktop to detect the hot files/directories, whose DLM locks are frequently referenced among the cluster.
You can get the maximal wait time per DLM lock, this helps you identify which hot files/directories should be decoupled for improving file access performance.
