Have you installed the gpfs.pm-ganesha package, and do you have any active NFS \
exports/clients ?

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

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,
Alvise
