Loading MIBs in hpux

[Sabin Mathew]

I was working with mrtg to monitor the disk usage in Hp-ux.
Could I know how I can load the mib /opt/OV/newconfig/AGENT-MAN/snmp_mibs/hp-unix

[Geoff Wild]

Add it to the top of your mrtg.cfg file:

LoadMIBs: /opt/OV/newconfig/AGENT-MAN/snmp_mibs/hp-unix

Rgds...Geoff

[Sabin Mathew]

Thanks for the reply.

I have added this line to the top of the .cfg file.

But when I run mrtg, it gives snmp error, unable to poll the OID that I specified.

Thanks,
Sabin

[Geoff Wild]

What are you polling for OID...

Here's how I do it (though I don't use the OVO mibs - but it may help):

more mrtg.cfg
EnableIPv6: no
LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt
WorkDir: /htdocs/mambo/mrtg/

Thanks again for the reply.

Here, the scenario is, mrtg is installed in a test server and I need to monitor the file system usage of another server in the production environment.

I created a .cfg file using the cfgmaker and it worked well for the network monitoring part.But for the filesystem monitoring, I am stucked up..

I just added the mib in the .cfg file and still its giving snmp error.
Please find below the error messsage.

I'll try those mibs tomorrow when I'm at work....

Rgds...Geoff

[Geoff Wild]

Couldn't get it to work - saw this on the net:

http://www.admins-tipps.net/management/mrtg_hpux.txt

AT the bottom, it mentions using a tool like getif to get the actual numbers for the disks...

Rgds...Geoff

[Sabin Mathew]

Thanks again for the reply and info.
I was just exploring the URL you provided; could see a getif install file.

" Following is a sample for the drive allocations. You must find out
the numbers yourself."

Does this mean, we need to find out the actual disk usage percentages or what? I am confused what does this 'numbers' mean..

Thanks,
Sabin

[Geoff Wild]

I believe - those are the disk id's...

Rgds...Geoff

[Geoff Wild]

Wow - getif seems to work - yet I can't make heads or tails of it...

Example, found this:

.iso.org.dod.internet.private.enterprises.hp.nm.hpnsa.hpnsaStorageCap.hpnsaSCDrv.hpnsaSCDrvTable.hpnsaSCDrvEntry.hpnsaSCDrvCurrentAvailable

.1.3.6.1.4.1.11.2.23.15.3.2.1.12

But, I get nothing when I connect...tried version 1 and 2c:

# snmpget -v 1 -c mysnmp myserver .1.3.6.1.4.1.11.2.23.15.3.2.1.12
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: iso.3.6.1.4.1.11.2.23.15.3.2.1.12

# snmpget -v 2c -c mysnmp myserver .1.3.6.1.4.1.11.2.23.15.3.2.1.12
iso.3.6.1.4.1.11.2.23.15.3.2.1.12 = No Such Object available on this agent at this OID

Rgds...Geoff

[Geoff Wild]

Ah - cool - got it....

I put the hpunix mib in C:\Program Files\Getif 2.3.1\Mibs as hpunix.MIB and deleted .index

The started getif...

Now I see more from the Mbrowser tab:

.iso.org.dod.internet.private.enterprises.hp.nm.system.general.fileSystem.fileSystemTable.fileSystemEntry.fileSystemBfree

but the lvols are:

.iso.org.dod.internet.private.enterprises.hp.nm.system.general.fileSystem.fileSystemTable.fileSystemEntry.fileSystemDir

Then click on start, and you will see the lvols:

Example, my /home is:

.1.3.6.1.4.1.11.2.3.1.2.2.1.10.1073741829.7

Looking at:

.1.3.6.1.4.1.11.2.3.1.2.2.1.6.1073741829.7

I see I have 139137 availabl3 (same as output from BDF).

To output in mrtg:

Target[sha1_home_disk]: .1.3.6.1.4.1.11.2.3.1.2.2.1.4.1073741829.7&.1.3.6.1.4.1.11.2.3.1.2.2.1.6.

Thanks for this again...

The community 'mysnmp' exists by default or should need to create it?


Thanks,
Sabin

[Sabin Mathew]

I have one more question...

Did you load the mib hpux in the .cfg file or these OIDs are readily available?

Could you send me the whole .cfg file?

Thanks,
Sabin

[Geoff Wild]

No - mysnmp - is my community name - default is public.

And yes - I loaded that MIB - here's the test mrtg.cfg I used:

EnableIPv6: no
LoadMIBs: /usr/local/share/snmp/mibs/hp-unix /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt

[Sabin Mathew]

Thanks for the cfg details.

When I tried snmpget using these particular OIDs, I am getting integers, but those are not same as I obtained from the bdf output..

Thanks,
Sabin

[Sabin Mathew]

Yes.....I could get the free and used i-node numbers...but not the usage in KB

Have you tried graphing these two values? In my graph, the plot is nil...

Thanks,
Sabin

[Geoff Wild]

Oops - sorry had the oid's reversed - should be 6 then 4:

Target[sha1_disk]: .1.3.6.1.4.1.11.2.3.1.2.2.1.6.1073741829.7&.1.3.6.1.4.1.11.2.3.1.2.2.1.4.1073741829.7:mysnmp@sha1

There is a log file you can see as well:

# more sha1_disk.log
1129221268 139137 524288
1129221268 139137 1 139137 1

1129220400 1 1 1 1
1129220100 1 1 1 1
etc...

Also - I changed
MaxBytes[sha1_disk]: 512000\

as my home is 512MB

Sorry about that..

Rgds...Geoff

[Sabin Mathew]

Thanks for the reply...

My .log file looks like this,

1129216800 0 0 0 0

Your log file has 1s instead of 0s, what does it mean?

Could you clarify the following?

1. While doing snmpget, I got this,
SNMPv2-SMI::enterprises.11.2.3.1.2.2.1.5.1073741828.7 = INTEGER: 50418

What does this integer mean? is this Kb,it doen't match to any of the parameters in the bdf output.

2.Apart from using the OIDs in the .cfg file, do we need to configure something in the target server?

3.I could find that, by changing 1073741828 to ********7..., we can find out other lvs.

Thanks,
Sabin

[Geoff Wild · Accepted solution]

the integer is the available space in kbytes - just compare it to a bdf output.

IE mine:

snmpget -v 1 -c mysnmp sha1 .1.3.6.1.4.1.11.2.3.1.2.2.1.6.1073741829.7
iso.3.6.1.4.1.11.2.3.1.2.2.1.6.1073741829.7 = INTEGER: 139137

bdf /home
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol5 524288 375902 139137 73% /home

Rgds...Geoff

[Sabin Mathew]

Thanks for the quick reply....

But in my case, its,

snmpget -v 1 -c public brksvx06 .1.3.6.1.4.1.11.2.3.1.2.2.1.6.10
73741829.7
SNMPv2-SMI::enterprises.11.2.3.1.2.2.1.6.1073741829.7 = INTEGER: 1079

and the bdf output is,

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol5 212992 52712 159288 25% /home

The only difference is you are using a different community name. Is it mandatory to create a community?

Are there any snmp settings at the target side?

Thanks,
Sabin

[Sabin Mathew]

Could you send me your snmpd.conf file?

Thanks,
Sabin

[Geoff Wild]

Intersting that yours is:

SNMPv2-SMI::enterprises

and mine is:

iso

Are you sure you have the right OID? did you use getif program?

do a full bdf - not just of /home.

In my snmpd.conf file - we only set 2 variables - community name and trap-dest:

get-community-name: mysnmp
trap-dest: 192.162.5.5


Rgds...Geoff

[Sabin Mathew]

Do we have getif for UNIX?
It seems, getif is not functioning in windows..

Thanks,
Sabin

[Geoff Wild]

No Unix - only windows - I downloaded getif v2.3.1 from:

http://www.wtcs.org/snmp4tpc/getif.htm

Rgds...Geoff

[Sabin Mathew]

I just ran the getif program.
Could you please tell me which number should I use in the mrtg cfg file?

I am attaching the screen as a word file.

It seems, getif returns the same OID that your systems has.

Thanks,
Sabin
