[gpfsug-discuss] NFSIO metrics absent in pmcollector

Dear Community,

I've activated CES-related metrics by simply doing:

[root at xbl-ces-91 ~]# mmperfmon config show |egrep -A4 'NFS|SMB'
        name = "NFSIO"
        period = 5
},
{
        name = "SMBGlobalStats"
        period = 5
},
{
        name = "SMBStats"
        period = 5
}

Despite that, I get no result for any nfs* metrics:

--------------------------------------------
[root at xbl-ces-91 ~]# telnet localhost 9084
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
get -j metrics nfs_read bucket_size 5 last 1
Error: no data available for query
.
Connection closed by foreign host.

[root at xbl-ces-91 ~]# mmperfmon query "nfs_read"
Error: no data available for query
.

mmperfmon: Command failed. Examine previous error messages to determine cause.
--------------------------------------------


I am pretty sure my collector is working correctly as it returns data for a different metrics:

[root at xbl-ces-91 ~]# telnet localhost 9084
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
get -j metrics gpfs_fs_bytes_read last 20 bucket_size 1
{"header" : {"bcount" : 20,"bsize" : 1,"t_start" : 1618912752,"t_end" : 1618912772},"legend" : [{"caption" : "gpfs_fs_bytes_read","semType" : 2,"aggrType" : "value difference between start and end of the bucket","type" : 4,"keys" : ["xbl-ces-91.psi.ch|GPFSFilesystem|lenovoxbl.psi.ch|perf|gpfs_fs_bytes_read"]},{"caption" : "gpfs_fs_bytes_read","semType" : 2,"aggrType" : "value difference between start and end of the bucket","type" : 4,"keys" : ["xbl-ces-91.psi.ch|GPFSFilesystem|lenovoxbl.psi.ch|tiered|gpfs_fs_bytes_read"]},{"caption" : "gpfs_fs_bytes_read","semType" : 2,"aggrType" : "value difference between start and end of the bucket","type" : 4,"keys" : ["xbl-ces-92.psi.ch|GPFSFilesystem|lenovoxbl.psi.ch|perf|gpfs_fs_bytes_read"]},{"caption" : "gpfs_fs_bytes_read","semType" : 2,"aggrType" : "value difference between start and end of the bucket","type" : 4,"keys" : ["xbl-ces-92.psi.ch|GPFSFilesystem|lenovoxbl.psi.ch|tiered|gpfs_fs_bytes_read"]}],"rows" :
[...]

Any clue ? Is the activation of NFSIO enough in the mmperfmon's config file (this is the first time I try to configure CES monitoring) ?

Thank you,
