 Posted: Thu Aug 14, 2008 5:10 pm Post subject: data coming up as nan |
 |
|
Folks,
I'm trying to generate a graph utilizing the samba.pl script from this forum. (The SNMP version.)
For some reason, after the graph is created initially, (and data is gathered initially), I get no more data gathering, and hence - no more data on the graph - all data points come up as 'nan.' In fact, after the initial generation of the graph with the initial data, there are not more entries in the log file from the samba script.
Here's the output from cacti.log, grepping 'samba':

Any thoughts? As can be seen, after that initial data gathering, no more data is aquired. The script runs fine on the command line.
Any help would be appreciated.
- Thanks,

There are so many create statements in this log, that it's hard to cope with.
Please veriyf, that "System Utilities -> View Poller Cache" shows the script. Please see 2nd link of my sig more more debugging infos (some of them will not apply to your case, bear with me)

Yes....I see the script in the poller cache view.
Here's the way I've got it set up:
my remote cacti client has the following in its snmp.conf file:
| Code: | #######
# samba monitoring
#######
exec .1.3.6.1.4.1.2021.55.1 Samba /opt/cacti/scripts/samba.pl Processes
exec .1.3.6.1.4.1.2021.55.2 Samba /opt/cacti/scripts/samba.pl Shares
exec .1.3.6.1.4.1.2021.55.3 Samba /opt/cacti/scripts/samba.pl Files
|
an
| Code: | snmpwalk -v 2c -c comm_name cacti_client .1.3.6.1.4.1.2021.55.1
|
run from the cacti server yields the following:
| Code: |
UCD-SNMP-MIB::ucdavis.55.1.1.1 = INTEGER: 1
UCD-SNMP-MIB::ucdavis.55.1.2.1 = STRING: "Samba"
UCD-SNMP-MIB::ucdavis.55.1.3.1 = STRING: "/opt/cacti/scripts/samba.pl Processes"
UCD-SNMP-MIB::ucdavis.55.1.100.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.55.1.101.1 = STRING: "17"
UCD-SNMP-MIB::ucdavis.55.1.102.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.55.1.103.1 = "" |
So I know I can get the data that I need. That appears to be working. It just seems that after the initial generation of the graph, in which I get the output below:

(and of course, everything looks great! I'm getting data, and the graphs have been created.) After this initial tease, I get no more data to my graphs. CONSISTENTLY. I remove the old graph. I start over. I tell the device to generate the samba graph. I look in the log file. When poller runs, I get an initial aquisition of data, as above, and the graph gets created. After that point, I get "Nan' data. Its weird. I know snmp is working, as can be seen above. But it seems like cacti refuses to make the effort to even try
to get any more data.
Any reason why this might be happening? An initial data aquisition followed by nothing?
- Thanks

This looks fine, up to now. When the poller is running at a later interval, Do you find | Quote: | | CACTI2RRD: /usr/local/rrdtool-1.3.0/bin/rrdtool update /opt/cacti-0.8.7b/rra/machine_samba_proc_419.rrd --template samba_proc N:17 |

? You've defined the rrd file using an interval of 60 secs, do you run the poller with the correct settings?

Actually, what I did was remove all instances of the samba template, and all rrds associated with it, and I reloaded them all - started over as if I had never had samba graphs to begin with.
And of course, the graphs came back in full force, and I was getting actual data. I wonder if the template got corrupted somehow? Could that be the issue?
Eitherway, the issue is solved now. I just had to redo it. Not a big deal, and actually it was a lot easier than picking through the log file.
- Thanks,

This would be a guess; so I'll drop that.
