BeeGFS monitoring daemon


Mon database reference


This page contains a description of all the measurements stored in the beegfs-mon InfluxDB with their fields and tags and what they mean.

meta


Key Data type Description
nodeID string ID of the node the point is related to.
nodeNumID int Unique numeric ID of the node the point is related to.
isResponding bool Node was responding when writing the point. If not, points are still written without data and this is set to false.
indirectWorklistSize int # of queued indirect tasks.
directWorklistSize int # of queued direct tasks.


highResMeta


Key Data type Description
nodeID string ID of the node the point is related to.
nodeNumID int Unique numeric ID of the node the point is related to.
workRequests int # of work requests processed during the measurement period.
queuedRequests int # of work requests queued during the measurement period.
netSendBytes int Bytes sent to other nodes.
netRecvBytes int Bytes received from other nodes.


storage


Key Data type Description
nodeID string ID of the node the point is related to.
nodeNumID int Unique numeric ID of the node the point is related to.
isResponding bool Node was responding when writing the point. If not, points are still written without data and this is set to false.
indirectWorklistSize int # of queued indirect tasks.
directWorklistSize int # of queued direct tasks.
diskSpaceTotal int Total disk space on all storage targets combined in bytes.
diskSpaceFree int Free disk space on all storage combined targets in bytes.



highResStorage


Key Data type Description
nodeID string ID of the node the point is related to.
nodeNumID int Unique numeric ID of the node the point is related to.
workRequests int # of work requests processed during the measurement period.
queuedRequests int # of work requests queued during the measurement period.
netSendBytes int Bytes sent to other nodes.
netRecvBytes int Bytes received from other nodes.
diskWriteBytes int Bytes wrote to storage targets.
diskReadBytes int Bytes read from storage targets.


storageTargets


Key Data type Description
nodeID string ID of the node the related target is on.
nodeNumID int Unique numeric ID of the node the related target is on.
storageTargetID int Unique numeric ID of the storage target the point is related to.
workRequests int # of work requests processed during the measurement period.
queuedRequests int # of work requests queued during the measurement period.
diskSpaceTotal int Total disk space on storage target in bytes.
diskSpaceFree int Free disk space on storage target in bytes.
inodesTotal int Total inodes on storage target.
inodesFree int Inodes available on storage target.
targetConsistencyState string HA target consistency state. Is either GOOD, NEEDS_RESYNC, or BAD.


clientOps


There are four measurements of the form (meta|storage)clientOpsBy(Node|User)
which contain the syscalls made to the corresponding node types grouped by User or Node.

Key Data type Description
node string IP address of the client node the point relates to in dot notation. Only in the ByNode measurements.
user string Local user ID of the user who used the client node the point relates to. Only in the ByUser measurements.
* int # of syscalls on the beegfs client during measurement period. There is one key for each type of syscall, but only if there occured at least one.
