DFM 4.0D23 dfmserver errors

[marcinl]

While searching for reason why not all performance counters are available I have found following problem:

All dfmserver*.log files contains only errors like below:

Sep 21 02:16:26 [dfmserver:ERROR]: [29018:0x3f8aba0]: fopen failed Nosuch file or directory

Sep 21 02:16:34 [dfmserver:ERROR]: [29018:0x4992ba0]: fopen failed Nosuch file or directory

I have no clue which file/directory it's trying to open.

Can anyone help?

Please provide "dfm diag" and check where the performance data is stored.

[marcinl]

Attached dfm diag output and ls -al for DFM and performance data directory.

I will also check the filesystem for errors.

This error could be due to deletion of some files from /opt/NTAPdfm/perfdata directory.

After the files are deleted server needs to be restarted for starting the collection of performance counters data.

Hi pagrawal,

Thank you very much for your answer. I have just checked history on the server and yes, the files in perfdata were deleted.

After restart DFM collects performance counters again.

Thx a lot.
