[Devmon] graphing sentry CDU temps

[crankshaft <cra...@oc...>]

Sorry just remembered the rest of the .rrd generator in 
message (after reading Jeremy's post):

<!-- DEVMON RRD : temperature 0 0
DS:TempValue:temperature(.*):GAUGE:600:0:U
temperature {TempValue}
-->

[Devmon] (no subject)

[crankshaft <cra...@oc...>]

Hi,

I'm having trouble pulling the values (mainly temperature) 
from a Sentry CDU power distro unit and storing in a rrd 
file for graphing. I've got two temp sensors plugged in 
(intake and exhaust) but it appears these two sensors use 
the same OID (enterprises.1718.3.2.5.1.6), but the first 
sensor has index / instance? number of 1.1, and the second 
one has 1.2 .
I can get the values to display on the status page of the 
devmon test as a table, and can get them from snmpget. I 
did have them inputting into .rrd and was able to graph 
the data, but whenever the temperature changed it seemed 
to generate another .rrd, the result being multiple graphs 
showing "flatline" dot / dash values of the temps at 22, 
22.5, 23 etc.
Is it possible to simply give the two sensors different 
mnenomics in the template/oids file such as:

intakeTemp :  enterprises.1718.3.2.5.1.6.1.1 : ????????
exhaustTemp :  enterprises.1718.3.2.5.1.6.1.2 : ????????

to use them in the message file to generate the.rrd and if 
so, what do I put in the ???????? section? I've tried 
branch and leaf, but get the 'No snmp data for oid' error 
in devmon.log and devmon-scan.log with branch and 'oid is 
a non-repeater' error with leaf. The docs Transform 
section says something about the INDEX transform but 
doesn't give an example of its usage.

The .rrd generator in templates/message is (off the top of 
my head):

<!-- DEVMON RRD temperature 00
DS:TempValue:temperature(.*):GAUGE:600:0:U
-->

where TempValue is the result of a MATH transform of /10:1 
on tempHumidSensorTempValue (which is 
 enterprises.1718.3.2.5.1.6).

The graph definition is the [temp] one in hobbitgraph.cfg, 
with the .rrd and ds0 substituted with temperature and 
TempValue.


thanks in advance,

Geoff

Are you *sure*? Can you provide the MIB file and a sample snmpwalk (preferably 
with the MIB known to snmpwalk)?

The intention was really only to support table data, but I agree that it is 
sometimes useful to use it for leaf data too, if you are saddled with badly 
designed MIBs.

Yes. Have a look at the data sent from some existing tests that have working 
graphs (e.g. if_load).

Can you provide the actual data you are sending? E.g. from:
bb localhost 'hobbitdlog hostname.testname'
(or the equivalent with xymon in place of bb/hobbit if you are on 4.3.x).

I think do_devmon.c should work fine without the '0 0', but all examples I 
have seen have had the '0 0'.

To be honest, I have no idea what either of these were for. "I found it like 
this". The majority of the perl/devmon portion of the RRD support was written 
by Eric Schwimmer, but with no implementation of the Hobbit/Xymon side, and 
very little documentation.

I wrote do_devmon.c, and I had no idea what to do with those ...

You need to start hobbitd_rrd with debugging enabled, e.g. by adding the '--
debug' option to the CMD in the task definion for rrdstatus.

[Devmon] Undocumented "<!--DEVMON RRD" graphing method?

[Jeremy L. <jla...@re...>]

Hi

I've created a template for an Infoblox DNS appliance, and I'm trying
to graph fan speed.  The OIDs are leaf nodes, and so I can't create a
table to do this.  Instead, I'm trying to fudge the equivalent output
by hard-coding the output that devmon normally creates.

I can't find any doco on how to do this, and so I suspect it's
undocumented.  So, my first question is, should I avoid this method?

The format appears to be this:

<!--DEVMON RRD: testname 0 0
DS:ds0:GAUGE:600:0:U
somename1 {value1}
somename2 {value2}
somename3 {value3}
-->

>From the source (do_devmon.c) I can't tell what the "0 0" is for, or
even if it's necessary.  The dm_tests.pm file shows these as "$dir
$do_max" but I can't find what "dir" means - an RRD option that I
can't find.  The do_devmon.c file seems to not need it, and discards
everything after the space before the "dir" field.

Either way, I can't seem to get RRD files created, and I don't know
where to look for parsing errors.  Xymon's rrd-status.log would seem
to be the place, but nothing relevant is showing up there.  Any ideas?

I guess I could go ahead and use the documented NCV strategy.  But I
wanted to be able to create RRD files without having to touch Xymon
configuration.

[Devmon] new release...?

[<lor...@bn...>]

Hi Buchan,

0.3.1-beta2...  I can't see it on sourceforge.
Or, is sourceforge the right place to look at?
If not, where should we point to?

And more in general, what are the future plans for devmon?
Any dates for a new or stable release? ;-)
 (i.e. 0.3.1-beta1 dates Jan 09).

Thanks a mill

Loris

You don't provide the version you are using, but I think anything but 
0.3.1-
beta2 or svn doesn't support the use of '*' as a multiplication operator, 
but 
'x'.

[Devmon] MATH transform uses only math/numeric symbols and an optional precision number

[ian n. <ino...@ho...>]

Hi,

i have been banging my head against a wall for 2 hours, but I cant work out what the problem is.


transforms below:


availableMem :     MATH     : ({hrStorageSize}-{hrStorageUsed}) * {hrStorageSize} : 0
usedMem :     MATH     : {hrStorageUsed}*{hrStorageSize} : 0
totalMem :     MATH     : {hrStorageSize}*{hrStorageSize} : 0

the variable which start with hr are defined in the oid file, others Im  creating on the fly. I have read articles which seem to say this is ok.

Can some one put me out of my misery please??

Before I look at the MIB, from your explanation, the last three numbers should 
be accessible in devmon by using the INDEX operator (as the index of the SNMP 
table). If not, you aren't looking at an SNMP table.

After looking for this MIB at mibdepot.com, it seems this 
(1.3.6.1.4.1.4874.2.2.20.1.8.8) is juniAaaSubscriberLocationSummaryTable, and 
each entry in the table has a juniAaaSubscriberLocationSummaryLocationIndex 
(1.3.6.1.4.1.4874.2.2.20.1.8.8.1.1) and juniAaaSubscriberLocationSummaryCount 
(1.3.6.1.4.1.4874.2.2.20.1.8.8.1.2).

If you can't get juniAaaSubscriberLocationSummaryLocationIndex, then you 
should use the INDEX operator on juniAaaSubscriberLocationSummaryCount.

[Devmon] Repeater table without primary column?

[Thomas K. <tk...@ne...>]

Hi,

is it possible to use a repeater table when there is no primary column?

E.g. I want to monitor the PPP sessions on individual interfaces
on a Juniper E320 BRAS system.

However there is no ifName or ifIndex column in this table. Instead the
the last three numbers in the returned OID is the interface name:

$ snmpwalk e320bras 1.3.6.1.4.1.4874.2.2.20.1.8.8
SNMPv2-SMI::enterprises.4874.2.2.20.1.8.8.1.2.3.1.0.1 = Gauge32: 4928
SNMPv2-SMI::enterprises.4874.2.2.20.1.8.8.1.2.3.1.0.2 = Gauge32: 3232
[...]                                           -----
                                                | interface name

Re: [Devmon] No multiple options in devmon tag

[Contreras, M. <Mar...@ti...>]

Hi Bucham

Thank you, once I get rid of the space the error disappear, but the threshold is not working as expected because I'm still getting the yellow alert for the "not_present" result . This is the line in bb-hosts file:

10.30.2.90      SERVER_1 #DEVMON:except(if_stat;ifName;na:Gi1/8|Gi1/16|Gi1/17|Gi1/18|Gi9/10|Gi9/ 11|G i9/13),thresh(fans;fanStatus;y:not_working;g:not_present)

I guess I'm missing something.

Because we have the same machine type with one and two fans so far we didn´t considered to change the default threshold file, but depending if the above option in bb-hosts doesn´t work we could try the setting in the opposite way, i.e. by default don´t alarm when "not_present" and customize bb-hosts for the servers with two fans installed.

Try and avoid spaces.

But, maybe we need to consider if by default the 'not present' status should have a different color by default in the 'thresholds' file for this template/test?

[Devmon] No multiple options in devmon tag

[Contreras, M. <Mar...@ti...>]

Hi

 

I´m running devmon-0.3.1-beta1 with xymon 4.3.0.beta2, when trying to use multiple options in devmon tag in bb-hosts file, devmon is complying.

 

The line I'm using is this:

 

10.30.2.90      SERVER_1 # DEVMON:except(if_stat;ifName;na:Gi1/8|Gi1/16|Gi1/17|Gi1/18|Gi9/10|Gi9/11|Gi9/13),thresh(fans;fanStatus;g:not present)

 

When running devmon the errors I'm getting are these:

 

/ # /opt/devmon-0.3.1-beta1/devmon --readbbhosts

[11-12-06@19:47:12] Unknown devmon option (,thresh(fans;fanStatus;g:not) on line 111 of /opt/xymon/server/etc/bb-hosts

Use of uninitialized value in concatenation (.) or string at /opt/devmon-0.3.1-beta1/modules/dm_config.pm line 1928, <$__ANONIO__> line 20.

Use of uninitialized value in concatenation (.) or string at /opt/devmon-0.3.1-beta1/modules/dm_config.pm line 1928, <$__ANONIO__> line 20.

 

Any idea why is this?

 

Cheers

What version? If anything but svn, this can be due to some other OID not being 
present, so check that all your OIDs active for this host are reporting 
values. In svn devmon now ignores empty OIDs if there was no error message 
from SNMP_Session.

Run devmon in foreground in a screen session with debugging?

Or, run devmon in foreground (-f) for one host (-h option) in print-only mode 
(-p). -h may only be available in svn, I can't remember if it is in the last 
beta released.

Did you create the transforms and exceptions files (they must be
present even 
if empty)?

Did you try increasing the verbosity and looking for relevant error
messages?

If you have sufficient logging verbosity, it should give you a hint as
to why.

[Devmon] VPN Monitoring for Cisco 2800 Series Routers

[Matthew N. <MNe...@sa...>]

Hello,
 
I am trying to make devmon monitor the count of vpn's that are active
on routers. This allows us to determine if the backup connections are
up/down.
 
My Code
 
xymon:/etc/devmon/templates/cisco-2800/dsl # cat message
{cipSecGlobalActiveTunnels.errors}
 
DSL Connections
 
Number of Active DSL Connections {cipSecGlobalActiveTunnels}

xymon:/etc/devmon/templates/cisco-2800/dsl # cat oids
cipSecGlobalActiveTunnels : .1.3.6.1.4.1.9.9.171.1.3.1.1 : leaf
xymon:/etc/devmon/templates/cisco-2800/dsl # cat thresholds
cipSecGlobalActiveTunnels       : red   : 0     : No Connections
cipSecGlobalActiveTunnels       : green : >0    : Number of Active
Connections is Normal: {cipSecGlobalActiveTunnels}
So far this does not work or return values. If I use snmpwalk I get a
value back with no issues. However, devmon isn't pulling the data.
 
Thanks,
Matt

Re: [Devmon] Errors when applying revision 228

Hi Buchan

>Does reverting to the '|x' version in dm_templates.pm make any difference?

Yes, currently the line (547) in dm_templates.pm for math test that is working in my installation is this:

$temp =~ s/\{\s*\S+?\s*\}|\s|\s\.\s|x|\*|\+|\/|-|\^|%|\||&|\d+(\.\d*)?|\(|\)\s*//g;

With no errors when launching devmon with option "readbbhosts"

In dm_tests.pm:

460: # Convert our math symbols to their perl equivalents
461:    $expr =~ s/\sx\s/ \* /g;  # Multiplication
462:    $expr =~ s/\^/**/g; # Exponentiation

I think you mean this change:

http://devmon.svn.sourceforge.net/viewvc/devmon/trunk/modules/dm_templates.pm?r1=208&r2=219

and the associated portion in dm_tests.pm:

http://devmon.svn.sourceforge.net/viewvc/devmon/trunk/modules/dm_tests.pm?r1=192&r2=195&view=patch

Which was replacement of '|x' with '|\sx\s'

This change was specifically to fix a bug affecting the use of the letter x in OID names used in MATH operators (where e.g. {index} would not work as the x would be recognised as a mathematical operator).

The next change to that file allowed the use of '*' as a multiplication operator as well.

I don't see why this should be causing a problem.

I have a few production servers running r214 without problem (which, granted, doesn't have the dm_templates.pm part), and my laptop has a clean checkout of trunk monitoring at least itself with linux-netsnmp template, with working if_load graphs.

I really can't see how this could have broken ...

Does reverting to the '|x' version in dm_templates.pm make any difference?

I'm seeing similar problems in a devmon installation, built a few days

[Devmon] Errors when applying revision 228

[Contreras, M. <Mar...@ti...>]

Hi

 

Last night I apply revision 228 but when running devmon with -readbbhosts option it started to complain about MATH function:

 

"MATH transform uses only math/numeric symbols and an optional precision number at /opt/devmon-0.3.1-beta1/templates/cisco-2800/if_dsc/transforms, line 6"

 

That line is as follows:

ifOutBps        : MATH          : {ifOutOps} x 8

 

(There is a space at both sides of x)

 

After checking the issue more in detail the problem seem to appear because two changes in line 547 of dm_templates.pm: deletion of "|\s"  and addition of  "|\sx\s"

 

I´m running devmon over a sparc solaris 10 box. 

 

Any ideas why is happening?

 

Cheers

 

MC

[Devmon] ProCurve template

[Colin C. <col...@gm...>]

Hi all

Does anyone have a ProCurve 2910al template that they don't mind
sharing?  If anyone has anything close, I'm happy to hack on it.

Also, is there a devmon equiv to TheShire, where people can share
templates?  A quick google didn't show up anything useful.

Thanks

snmpwalk -c public -v2c 0.0.0.0 IF-MIB::ifHCInOctets.10142
IF-MIB::ifHCInOctets.10142 = Counter64: 24810748924740

in html :
Gi0_42 2866263564:1534931186

so it's very different ... ;( I'm still looking.

[Devmon] Cisco Crypto VPN Monitoring

[Matthew N. <MNe...@sa...>]

Hello,
 
I'm trying to monitor crypto vpn sessions on the cisco 2800 series
routers. I have tried tons of combinations to try and get this to work,
but have had no luck. I need to monitor this OID and grab an alarm
anytime there is 0.00 no connections. It will pull data, but tends to
only show "yellow" as the status. DEVMON logs shows No SNMP data found
for cipSecGlobalActiveTunnels.

Have you tried adding an entry to the exceptions file?

I think the OID in question would have to be the primary repeater for that to 
work though.

If it can't be the primary repeater ... it might be an idea to file an 
enhancement request for this, and I will try and get to it.
