Hello Dorigo,
in contrast to the basic Spectrum Scale metrics, the NFS and SMB sensors
rely on a proxy mechanism that provides the metrics out of the CES stack.
In case you have not used the installer, you may miss some steps.
- Please check if you have the requires packages installed.
(For example gpfs.pm-ganesha-10.0.0-2.el8.x86_64 or similar for NFS)
- The config section should have the "Generic" keyword, like this
{
name = "NFSIO"
period = 10
restrict = "cesNodes"
type = "Generic"
},
See here in the KC:
https://www.ibm.com/docs/en/spectrum-scale/5.0.5?topic=tool-enabling-protocol-metrics
/var/log/zimon/ZIMonSensors.log may provides some additional clues as
well.
Mit freundlichen Grüßen / Kind regards

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 ZjQcmQRYFpfptBannerStart

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" :

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,
