weblogic monitoring via snmp or custom scripts?

[davidvincent]

As explained at http://e-docs.bea.com/wls/docs81/snmpma ... ml#1072184.

Is your use community name "community_prefix" you only get data about the admin server.

If you use "community_prefix@server_name" you get data about server_name.

If you use "community_prefix@domain_name" you get data about the admin and all managed servers.

If you use this "community_prefix@domain_name" as a community name, datas are indexed per instance with an index value corresponding to the match of this regexp /enterprises.140.625.340.1.1.(.*)/.

Hi All,

I tried to set up BEA monitoring using those templates and still have some issue with poller.

The cacti version is cacti-0.8.6j

The SNMP Cache items look fine. But Poller Cache Items do not have anything shown on the graph.

I turn on the Debug and there is no error related to it.

I run php cmd.php hostid hostit and the issue is the same.

The hostid is 23. Is the following data right on mysql?

mysql> select * from data_local;

I can not find record on poller_item related to the graph and Data source debug information is:

Looks like Data Source also has some issue.

Could somebody provide any help on how to trouleshooting?

Thanks in advance,

Hi All,

I fixed the issue. It is related to snmp_qurey xml file.

The original <oid_index_parse>OID/REGEXP seems do not work.

Regards,
Yao

[clockwork]

This looks great and potentially a huge win. Where are you guys getting your snmp xml files ? Are you building them by hand ? Does anyone have a prebuilt set that would work for weblogic 8.1.5 ?

Also has a side note, if your doing snmp for the system on port 161 and you put weblogic on some other snmp port, what sort of setup are you going with as far as snmp proxy ? (net-snmp on linux/unix)

[mwarchut]

Hi All,

Can I ask what you did to fix this?? Thanks

Mike

[davidvincent]

The original <oid_index_parse>OID/REGEXP will work or not depending the way your php/snmp plugin resolves parts of numerical oids to names.

Most implementations will resolve at least this part :
.iso.org.dod.internet.private.enterprises
.1.3.6.1.4.1

Then some will know about Weblo, and will resolve all of that :
.iso.org.dod.internet.private.enterprises.bea.wls
.1.3.6.1.4.1.140.625

Others dont even know about BEA and will return this :
.iso.org.dod.internet.private.enterprises.140.625

You must adapt the OID/REGEXP depending on how far your php/snmp plugin resolves oids to names.

Regards,
David.

[Tommi]

The original <oid_index_parse>OID/REGEXP will work or not depending the way your php/snmp plugin resolves parts of numerical oids to names.

So, as my system gives with snmpwalk as seen below, I should be able to use the "<oid_index_parse>OID/REGEXP" part as it is delivered?

Original setting:
<oid_index_parse>OID/REGEXP:enterprises.140.625.340.1.1.(.*)$</oid_index_parse>

Code: Select all

snmpwalk -v 2c -c pharse asennustesti:17005 .1.3.6.1.4.1.140.625.340.1.1
SNMPv2-SMI::enterprises.140.625.340.1.1.32.102.50.100.53.52.101.48.57.97.57.56.55.52.49.57.56.57.51.53.51.97.50.49.49.97.99.55.49.53.53.50.100 = STRING: "f2d54e09a98741989353a211ac71552d"

Still cacti can't understand what it is getting from the WLS. Verbose Query ( Console -> Devices -> (Edit) ---> (Verbose Query) ) gives me "No SNMP data returned" (see below). But snmpwalk gives data, so the problem is on the xml-file?

I just don't know what to check next, I have tried different OID/REGEXP settings (from full numeric to bea.wls).

Code: Select all

+ Running data query [16].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/sunjvm.xml'
+ XML file parsed ok.

Btw. If someone is looking for the MIBs of weblogic (like i was...), you can found them here -> http://edocs.bea.com/wls/docs92/snmp/index.html (beware, it's a java-app, over 2 MB big)

Hi...

Tried uploading the template provided into cacti. The template loads OK, but when I try to create graphs, I get the following error....

Notice: Undefined variable: column_counter in /usr/share/cacti/site/graphs_new.php on line 876

No errors are posted in the cacti logs(/var/log/cacti/cacti.log

I really have no idea how to track this down... any suggestions appreciated....

thanks

[scott.russell]

hi,
I managed to track down that the following file was missing in my install...

/usr/share/cacti/site/resource/snmp_queries/Weblog_cluster.xml

I renamed the file cacti_data_query_weblogic_cluster.xml to Weblog_cluster.xml. And now I get the following error..... I am probably doing something silly... any suggestions appreciated....

Sc0tt.....

[scott.russell]

Hi,

Sorry, I think I have been thinking out loud via email. Got past the installation issues...

I basically copied the correct files to the correct place. No renaming required!. So brain dead today. I still have an issue on the OID's for the weblog-cluster.xml, but could be they have changed since 8.1(I am using weblogic 9.2). I will investigate and try to start thinking inside my head instead of here....

apologies to all... and thanks for the scripts...

Sc0tt....

[scott.russell]

Folks,
I seem to have everything correct now, but my graphs are empty. I have done an snmp walk and everything seems fine. But when I do a "Data query verbose output" from the cacti console. The values returned are all blank. I am guessing there is an issue in the xml file, but I am at a loss to know what it is....Any help appreciated....

Folks,
I have managed to solve my issue. Seems that my regex was incorrect. In the file sunjvm.xml, I changed the regex as follows:-

before
<oid_index_parse>OID/REGEXP:enterprises.140.625.340.1.1.(.*)$</oid_index_parse>

After
<oid_index_parse>OID/REGEXP:1.3.6.1.4.1.140.625.340.1.1.(.*)$</oid_index_parse>

This all seems to work. Output from the Data query debug screen below for reference....

Many thanks...

I tried to run this on the server which host weblogic but it didnt return any values either:

Code: Select all

snmpwalk -v 1 apollo -c myshipserv .1.3.6.1.4.1.140.625.340.1.1

I'm not exactly sure what to do next.

Also on the weblogic side, I followed the 1161 port for the SNMP agent but got confuse with the snmp manager, so I put the IP address of the Cacti server and the snmp port that i use. (im not sure if that the right value)

Would you be so kind enough to explain it in a simpliest way possible for I am new in to this SNMP trapping.

Thanks.

[scott.russell]

hi,
I think port 1161 is used by weblogic... check as follows(unix/linux only):-

Port 1161 is used by weblogic. Use 1162 instead...(change in weblogic console, then stop/start all admin and managed servers)

Then use this command:-

snmpwalk -v 1 -c apollo@mydomainname myshipserv:1162 .1.3.6.1.4.1.140.625.340.1.1


where:-
appollo = snmp community string
mydomainname = your weblogic domain name
myshipserv = your server
1162 = snmp port your server is listening on


give it a go and let us know if you can get at least snmpwalk working and we can go from there...

Sc0tt....
