file system Metrics

Every 10 seconds, the collectd service uses a HPE Data Fabric plugin to gather the following file system metrics on each node in the cluster.

Name	Description
mapr.fs.bulk_writes	The number of bulk-write operations. Bulk-write operations occur when the primary file system container aggregates multiple small file writes from one or more clients into one big RPC, before replicating the writes.
mapr.fs.bulk_writesbytes	The amount of MB written by bulk-write operations. Bulk-write operations occur when the primary file system container aggregates multiple small file writes from one or more clients into one big RPC, before replicating the writes.
mapr.fs.kvstore_delete	The number of delete operations on key-value store files which are used by the CLDB and HPE Ezmeral Data Fabric Database.
mapr.fs.kvstore_insert	The number of insert operations on key-value store files which are used by the CLDB and HPE Ezmeral Data Fabric Database.
mapr.fs.kvstore_lookup	The number of lookup operations on key-value store files which are used by the CLDB and HPE Ezmeral Data Fabric Database.
mapr.fs.kvstore_scan	The number of scan operations on key-value store files which are used by the CLDB and HPE Ezmeral Data Fabric Database.
mapr.fs.local_readbytes	The amount of MB read by applications that are running on the file system node where the data resides.
mapr.fs.local_reads	The number of file read operations by applications that are running on the file system node where the data resides.
mapr.fs.local_writebytes	The amount of MB written by applications that are running on the file system node where the data resides.
mapr.fs.local_writes	The number of file write operations by applications that are running on the file system node where the data resides.
mapr.fs.read_bytes	The amount of data (in MB) read remotely.
mapr.fs.read_cachehits	The number of cache hits for file reads. This value includes pages that file system populates using the readahead mechanism.
mapr.fs.read_cachemisses	The number of cache misses for file read operations.
mapr.fs.reads	The number of remote reads.
mapr.fs.statstype_create	The number of file create operations.
mapr.fs.statstype_lookup	The number of lookup operations.
mapr.fs.statstype_read	The number of file read operations.
mapr.fs.statstype_write	The number of file write operations.
mapr.fs.write_bytes	The amount of data (in MB) written remotely.
mapr.fs.writes	The number of remote writes.
