CPU monitoring for Sun systems

Has anyone out there been able to get CPU monitoring working for Sun servers? I have had some success with monitoring disk, memory and network by using the Host Resources MIB provided with UCD-SNMP (Net-SNMP). However CPU will not show up. Any ideas? Is this possible?
Thanks.

I have a number of SUN servers running Solaris 9 and a couple of workstations running Solaris 9 x86. I currently can only see the network interfaces. I have been on various SUN sites to check how to configure SNMP on these boxes but I am still no further forward. I would like to monitor Volume usage memory and CPU usage as well as the interfaces. Any help would be appreciated

I'm using Red Hat vs9 and have been running around trying to get CPU Utilization working with Orion with net-snmp. And the reason that this does not work is because Orion obtains it's CPU stat by searching the value correspondint to the hrProcessorLoad OID located in the HOST-RESOURCES-MIB.txt file.

And for Linux (and I'm sure for Sun), this hrProcessorLoad OID is not implemented. So we can't do it.

Please correct me if I'm wrong. But I've posted this issue on several forums and keep on getting the same result, that hrProcessorLoad OID is not implemented in net-snmp (ucd-snmp).

Does SUN and Linux have a different MIB that provides CPU Load ?
We have not seen one.

If so, please forward the details to development@solarwinds.net

I don't know much about MIBs, however, I did use the MIB scanner utility in the Engineer's Toolset, and scanned a Linux machine running net-snmp and was able to obtain drive space info, memory, and all sorts of other goodies. Isn't this something Solarwinds can do as well to obtain the proper MIB? I'd be glad to assist.

I sent an email today with the snmp MIB for CPU and Memory status on Linux. And a dump of the data. CPU load is reported with 3 values but the 1st value could easily be taken for the 1 minute server load, or for pure CPU load derived mathematically from the CPU idle value.

I feel on unix/linux boxes the 1 min avg server load would be the more valuable figure as CPU idle fluctuates so much.

A 1-minute load is only good if you're polling the server every minute or so.

If you polled every 5 minutes on a 1-minute load, it would be very likely to miss a potential CPU-impacting event during the other four minutes not measured by the poll.

Any idea when these new MIBs might be working ?

DonYonce

All,
We have begun testing the "UCD MIB" for CPU load and Memory on Linux, Sun, and HP machines. The 1 minute stat will often show incorrect numbers, but the five minute average seems to be correct.

We will be implementing CPU Load in Orion using the UCD 5 minute decaying average.

Also, the percent memory will be based on the machine's physical memory. For example: if a UNIX machine has 50MB of memory and is using all 50 MB plus an additional 25MB of swap space, the percent utilization for memory will be 150%. This is similiar to the method used in Orion for Windows servers.

We can provide a pre-release to beta testers Monday March 29th.

Support for Net-SNMP agents on Sun , HP-UX, Linux, Red-Hat, etc. is available in Orion NPM version 7.2.

The pre-release of 7.2 can be downloaded from ftp2.solarwinds.net/.../SolarWinds-NetPerfMon-V7-SLX.exe

Note: This link is for SLX customers only. If you would like a V7.2 beta for the SL100, SL250, SL500, or SL2000, please contact SolarWinds Support at (918) 307-8100.

Does this new version still require you to load something similar to net-snmp on an HPUX machine, or will this new version get the disk/cpu/mem info with the default HPUX snmp agent that runs?

I downloaded the net-snmp for HPUX, but I was a bit confused on how to replace the default SNMP agent with the net-snmp agent, the files see very similar and I'm not sure if you just need to move them into place. I'll admit I haven't read much up on it, but if anyone knows of an article that would help me with this, or if its not needed per my above question even better.

Thanks,

I did for me on my HP-UX machines. But the net-snmp install is easy and source forge even has binaries if you don't know how to compile it yourself.

How is the 7.2 testing going? Any ETA on the release?

Actually I"m getting very bad cpu utilization number some upwards of 1750%

DonYonce

Contact SolarWinds support for a pre-release of Orion 7.2
Also, we have seen some SNMP agents on Sun machine report incorrect CPU utilization.

jpedraza

I think I've the same problem with AIX machines. The network has 690 and 650 machines some of them are virutal partitions. The processor graphics don't show anything and the memory poller table always shows the -1 value.

The machines are running AIX 5.2.

Anyone has worked with this servers or has the workaround for this problem?

Thanks

When is the ETA of the full release of the Orion 7.2?

bleearg13

I am getting very inconsistent results using 7.2 and monitoring CPU on both Linux and FreeBSD machines. Some CPU numbers I am getting are over 1700%. I am not so sure how useful the new integration is at this point if the values being reported are obviously incorrect.

I have still not received an answer, either on the forum or via support, regarding the specific OID or OIDs that Orion polls to get this information. Does *anyone* know? (hrProcessorLoad obviously doesn't work).

gallo007

Does the 7.2 beta have the ability to monitor Linux, Sun CPU?

I have downloaded net-snmp 5.2 source code onto one of our Solaris 9 boxes and after reading the readme.solaris from the package and following Bruce Shaw's excellent information). Here are the exact commands I used to build and install it on Solaris 9 (for any of you Wintel people like me who need to know the Unix commands).

----------------------
bash
PATH=/usr/sbin/bin:/usr/local/bin:/usr/sfw/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/OBSDssh/bin:/usr/ccs/bin
./configure --with-mib-modules="host disman/event-mib ucd-snmp/diskio smux agentx mibII/mta_sendmail" --with-cc=gcc
make
su root
bash
PATH=/usr/sbin/bin:/usr/local/bin:/usr/sfw/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/OBSDssh/bin:/usr/ccs/bin
make install
# add SSL libraries
/usr/bin/crle
find /usr -name "libcrypto*" –print
/usr/bin/crle -u -l /usr/local/ssl/lib
/usr/bin/crle
make test
snmpconf -g basic_setup
snmpconf –i
/usr/local/sbin/snmpd
snmpget -v 1 -c public localhost sysUpTime.0
snmpwalk -v 2c -c public -m ALL localhost .1.3 | more
----------------------

To troubleshoot start SNMPD with this command:
/usr/local/sbin/snmpd -f –L

We are using SW 7.2.65

Everything works, as long as you ignore the swap/memory calcuation issue described here: www2.solarwinds.net/.../topic.asp

Hope that helps.

do you have a problem with snmp hanging on volumes in 5.2?

We had that problem but when I built it with the commands above, it worked fine. I think one of the difference with our attempts before was using linked libraries instead of the static libraries used above.

iceman

We have Dell Servers running Linux. We have installed NET-SNMP 5.03.

Solarwinds sees the the CPU %, but the % stays static never moves up or down.

Has anyone seen this issue?

Mbuna

The NET-SNMP agent on HPUX isn't recommended for people running NNM or OVO as they are specifically built with the Emanate agent in mind, and that agent is in fact installed on monitored servers when you install the OVO agent.

This agent does provide CPU, Disk and Memory utilization already and I've sent Orion the correct MIB for this.

I'm still unable to get CPU, Disk, Memory on Sun machines. Has anyone gotten this to work on the standard Sun snmp agent?

axis007

The CPU load status never changes when monitoring Linux(RHEL3.0U4),seems like a bug? I'm using Orion 7.8

sandeep

Hi,

I'm new to Orion. We are able to monitor Windows but Linux(Fedora Core 1) is only partially monitored.

I'm using net-snmp. It doesn't show up CPU and Memory utilisation.

Can anyone help us with some default configuration that need to be done.

We are using Public as community string.

Await ur reply.

Sandeep

Sorry Sandeep - I am not a Linux Guru....

Orion was originally intended as a Network Monitoring tool.
The Server monitoring was added as a free add-on/bonus.
As such it does not support the same number of MIBs &/or detail as the Cisco devices.
All I can suggest is to do a search for Linux in this forum to see what others have done to make this work.
