Performance monitors

Good day all forum member!

I'm running GlancePlus option (g) - Process List and I saw the below message:

RED ALERT file table nearst full.

What file table is or how can I know which table is nearst full? The bdf command does not shows any disk full or to be fulled.

Help will be appreciated.

Check the following kernel parameters with SAm:
1) file_pad -- file table entries reseverd for superuser
2)maxfiles
3)maxfiles_lim
4)nfile
5)nflocks

Before changing these parameters I think it would be prudent to have a look at this link.

There should be an OS table that keeps track of information on all files that are being opened for the entire server. Such OS table is pre-allocated in size and could hold up to a definite number of entries. As there are more files being opened, this OS table starts filling up and before it used up the last available row record you'll see an alert message from Glance. The OS system table I described is the file table, its size can be enlarged by increasing the kernel parameter "nfiles".

Hope this help explaining what file table is.

Augusto,

If you are getting this ALERT while using 'g' option
in glance, just press 't' to get a "Systems Table Report"
It will show you the current utilization of system tables
monitored by Glance. The corresponding kernel
parameters are shown as well.

While using 't' option, you can get more information
about particular metrics (kernel parameters in this case)
by using 'h' command (for help). Select the first item,
"Current Screen Metrics" and then select the system
table that you are interested in.
