Cisco ACE Module Template

dmcdonald · **Posted:** Thu 21 Aug, 2008 6:55 am

This template needs a bit of work. All of the contexts can be mapped using ContextID's and run with a single command, but I haven't written the discovery piece for that yet.

Code:

$head_lines .= <<ECHO
#.....................................................................
# Router processor utilization.
#
      
ECHO
;
snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-SMI-V1SMI.my");
snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-TC-V1SMI.my");
snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-PROCESS-MIB.my");

my %cpu;

my (@temp) = snmpwalk($router,$v3opt,'cpmCPUTotalMonIntervalValue');
foreach my $tempi(@temp) {
   $tempi =~ /(\d+):\d/;
   my $instance=$1;
   my ($duration) = snmpget($router,$v3opt,"cpmCPUMonInterval.$instance");
   my $target_name=$router_name.".cpu".$instance;

Hi,

Is there an update finished version of this template, I have a requierment to monitor some ACE blades and was just checking to see if this would be fit for the purpose.

Any help would be great.

Thanks

Tim

No, I haven't written the multi-context piece. As written, this will monitor a single context, meaning you need to create an snmp user and policy on every context to be monitored, not just the admin context.

Patches welcome!

HI Daniel,

Thanks for the update.

I currently have a problem where by I can not get cfgmarker to use this template or any other template, I have added the template name to the --if-template and --host-template lines in the cfgmaker file and then dropped the file ir.tp or .htp in to the same directory as the cfgmaker file, but no luck.

Must be doing something wrong somewhere, I have had alook around steve forum plus other trying diff things but getting no where fast, any help or pointers would be great.

Not a programmer but don't like it when things get the better of me.

Thanks
Tim

I posted a sample cfgmaker command on the mrtg users newsgroup recently:

usr/bin/cfgmaker --if-template=iosv3.iftemplate --ifref=name --interfaces --host-template=iosv3.template --subdir=site1/HOSTNAME --username='foo' --authkey='0x21de...' --authproto='sha' --privkey='0xa897...' --privproto=aesfcb128 --output=/var/mrtg/cfg/site1/site1-router.cfg 'foo'@site1-router.example.com::2:1:1:3

This one should be a host-template

You might need to edit the template to remove Directory statements if you are not using --subdir

Hi Daniel,

Thats for the info, finally worked it out and got MRTG to use the templates ok. So i have tried to use you ACE template, I am further on with it, but I am seeing this error, have you any idea what it may relate to

Unknown SNMP var cpmCPUTotalMonIntervalValue
at (eval

line 14
Unknown SNMP var cpmCPUMonInterval.
at (eval

line 18
Unknown SNMP var cpmCPUTotal5secRev
at (eval

line 50

I have found the MIBs in the template on the web and pointed the template to them as per below

snmpMIB_to_OID("/MRTG/MIBS/CISCO-SMI-V1SMI.my");
snmpMIB_to_OID("/MRTG/MIBS/CISCO-TC-V1SMI.my");
snmpMIB_to_OID("/MRTG/MIBS/CISCO-PROCESS-MIB-V1SMI.my");

snmpMIB_to_OID("/MRTG/MIBS/ENTITY-MIB-V1SMI.my");
snmpMIB_to_OID("/MRTG/MIBS/CISCO-ENHANCED-MEMPOOL-MIB-V1SMI.my");

I am just not sure sure why the error is showing up, the .cfg file looks OK, but it does not generate the .ok file, I asume that is because of the above error.

Any ideas would be helpful.

Also does this template collect number of connection for real servers, I have had alook at it and don't think it does, do you have a template to do that by any chance to save reinventing the wheel..

Thanks for the help

Tim

Hi Daniel,

OK, fix that, I was using the wrong MIB by the looks of it.

snmpMIB_to_OID("/MRTG/MIBS/CISCO-PROCESS-MIB-V1SMI.my");

Tried this one and I do not get the error now.

snmpMIB_to_OID("/MRTG/MIBS/CISCO-PROCESS-MIB.mib");

Still got a problem thou, does not seem to be able to graph the CPU, seeing this error in the MRTG log, it is updating the .ok file now.

ERROR: Target[10.90.0.121.cpu1][_IN_] ' $target->[0]{$mode} ' did not eval into defined data
ERROR: Target[10.90.0.121.cpu1][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data

Also I had this error in the MRTG log after fixing the other error

ERROR: Line 58 (<TABLE>) in CFG file (c:/mrtg/mrtg/bin/cfg-files/10.90.0.121.cfg) does not make sense

Had a look atr the cfg file and changed it to look like this, which solved the error I was seeing.

PageTop[10.90.0.121.cpu1]: <H1>WWK6509ACE-1 Processor Load</H1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>WWK6509ACE-1 </td>
</tr>
<tr>
<td>Location:</td>
<td> </td>
</tr>
</table>
</div>

Cheers

Tim

The 'did not eval into defined data' error would indicate that the required OID is not supported by your device.

The '<TABLE>' error is because those lines following PageTop should all start with a space, which seems to have been removed in the code above (because it is not in a [code] tag)

dmcdonald · **Posted:** Mon 16 Mar, 2009 5:59 pm

I've re-written my template to pull more useful things. If there are other OIDs that someone might find useful, please let me know.

This needs to be run once per context. So, for example, if you have three contexts, you might do something like this:

Code:

/usr/bin/cfgmaker --if-template=ace.iftemplate --ifref=name --interfaces --host-template=ace.template --subdir=site1/HOSTNAME --username='foo' --authkey='0x75' --authproto='sha' --privkey='0xed' --privproto=aescfb128 --contextname=context1 --output=/var/mrtg/cfg/site1/context1.site1-ace-left.cfg context1@site1-ace-left.example.com::3:1:1:3
/usr/bin/cfgmaker --if-template=ace.iftemplate --ifref=name --interfaces --host-template=ace.template --subdir=site1/HOSTNAME --username='foo' --authkey='0x75' --authproto='sha' --privkey='0xed' --privproto=aescfb128 --contextname=context2 --output=/var/mrtg/cfg/site1/context1.site1-ace-left.cfg context2@site1-ace-left.example.com::3:1:1:3
/usr/bin/cfgmaker --if-template=ace.iftemplate --ifref=name --interfaces --host-template=ace.template --subdir=site1/HOSTNAME --username='foo' --authkey='0x75' --authproto='sha' --privkey='0xed' --privproto=aescfb128 --contextname=context3 --output=/var/mrtg/cfg/site1/context1.site1-ace-left.cfg context3@site1-ace-left.example.com::3:1:1:3

I tried to cram the multi-context detection into the template, but it was just too hard. So I wrote it into my wrapper script that generates the cfgmaker lines for me. My wrapper is probably too hard to sanitize enough that it can be shared, but this host-template should be generic enough...

Since the same vlan might be found in multiple contexts, I also wrote an interface template that made that adjustment. It also ignores the NoHC directive that would be put in without the iftemplate. The ACE has working HC counters, but doesn't have a working ifSpeed or ifHighSpeed OID.

Code:

# 
if ($if_ok and $if_snmp_descr !~ /(unrouted|Stack)/ and $if_snmp_descr !~ /Null/i) { 
$target_name .= "." . $$v3opt{contextname} if exists $$v3opt{contextname};
$target_lines .= <<TOPPART

TOPPART

# Only add to big brother if it is a routed interface or a trunk line, not a "regular" vlan interface
if ($if_ip || $if_cisco_trunk) {
   $target_lines .= <<IPPART
bb*host[$target_name]: $router_name
IPPART

} else {
# if it is a "normal user port", then mark it with the service name "bw"

Hi Daniel,

Wonder if you can help me out here, I have been trying to get your new template to work, some of it works ok arounf interface stats, the parts around CPU, Current connection, Total Connections, Op and admin state don't work.

I am getting the below errors in the mrtglog

Must be doing something wrong but can't figure out what, SNMP is not my strong point but learning alot about it curently.

Any help would be good.

On a side note if a run an SNMP walk fiind the above in the the walk and then graph them in that tool it works OK, I have check the number string on the end of the SNMP var above and that seems to be OK, so I am assuming the issue id around the SNMP var name bit at the begining.

Any help would be great

Thanks in advance

Tim

You may need to use LoadMIB: to load in the Cisco MIBs, but which one I'm not sure as I don't use this. Also read the abovbe posts about the SnmpMIB_to_OID function changes.
