kenel parameter real time monitoring

[???_185]

Hi
i want to know that kenel parameter real-time monitoing.(hpux 11.11)
- maxdsiz_64bit, maxssiz_64bit, maxtsiz_64bit

what command is usable?

[Steven E. Protter]

Shalom,

Some kernel parameters actual use values can be monitored with Glance gpm.

Glance is a pay for add in product that you can use in trail form on the Application CD's for HP-UX for 60 days.

To get application cd's you need a software contract.

you can use gpm to monitor some parameters.

Glance (and GPM) (i'm using version C.03.70 on HP-UX 11i v1) will show real time utilization of the following kernel-related tables:
nproc
nfile
shmmni
msgmni
semmni
nflocks
npty
nbuf

so, unfortunately, it won't help in your case.

but i'm not sure that it even could, because all the parameters you list are "per process" parameters, i.e., they specify the maximum size for dynamic data, storage, and text segments (respectively) for any ONE process. thus, there's no real-time utilization value that corresponds to these parameters.

hope this helps...

For the parameters you mentioned (maxdsiz_64bit, maxssiz_64bit, maxtsiz_64bit), these are upper limits for all programs so they do not change or get "used up". You can see all the current parameter values in real time with kmtune.

[Alessandro Bocchino]

Usually you have specifications from the software vendor about the required value for these parameters.

Anyway, since they are just an upper limit
and do not steal themselves system resources you can simply set up a "comfortably high" value, such as the amount of RAM in the system, and forget about them.
