RMON Group 1 Etherstats - Templates

stevew · Joined: 17 Aug 2004 Posts: 26 Location: London

I (unfortunately) still deal with quite a few managed hubs (in this case the Cisco Fasthub 424M) that can't really be monitored via the interface MIB. However they do present good info in their RMON MIB.

These templates (and a query based on the "interface.xml" query) should allow for creating graphs for any device that supports the standard RMON Group 1 Ethernet statistics MIB (from RFC 2819).

Screenshot of graphs attached.

Hi Luc,

I've just imported all successfully - except the data query which isn't in good condition. I'll post a new copy tomorrow when I get to work.

Which templates are you having trouble with?

I have recreated the tarball on a different system and updated it in the original post.

I'm very interested in this Cacti script, and have imported all the files into v0.8.6f on Windows. All imported ok, but the data query for the RMON Stats says 'Could not locate XML file'.

The query file (as imported) is named;

cacti_data_query_rmon_interface_statistics.xml

Yet the script being referenced in the data query is;

rmon-grp1-etherstats.xml

I have tried renaming the script, but Cacti still says it cannot be located.

Any ideas?

i had the same problem than tman but when i changed file name, it was OK
me i have another problem
i create a device and in associated data queries, i choose "Rmon Interface Statistics"
in status of this data query i have Success [0 items , 0 rows]. I think this result is not normal
when i want to create a graph, i have these lines :
Warning: reset(): Passed variable is not an array or object in cacti_path\graphs_new.php on line 534

Warning: Variable passed to each() is not an array or object in cacti_path\graphs_new.php on line 535
Data Query [RMON - Interface Statistics]

Warning: reset(): Passed variable is not an array or object in cacti_path\graphs_new.php on line 610

Warning: Variable passed to each() is not an array or object in cacti_path\graphs_new.php on line 611

and :
This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.

if i choose to run this data query in debug mode, page load but nothing happen

i use cacti 0.8.6f on a windows XP

Ok, sorted out the XML file location problem, but when I add the data query to the device, I now get the following errors;

Notice: Undefined index: oid_index in C:\Inetpub\wwwroot\cacti\lib\data_query.php on line 156

Notice: Undefined index: oid_index in C:\Inetpub\wwwroot\cacti\lib\data_query.php on line 159

Warning: Variable passed to each() is not an array or object in C:\Inetpub\wwwroot\cacti\lib\data_query.php on line 513

Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\wwwroot\cacti\lib\data_query.php:156) in C:\Inetpub\wwwroot\cacti\host.php on line 110

Not quite the same as a2line59, but it isn't working!

I'm running a fully patched 0.8.6f by the way.

RMON is not only for HUBS, it provides much more info on switched Ethernet ports than the generic interface MIB.

Started experimenting with this package, info comes soon...

This package seems like broken.

I am going to play a little around it, it may be resurrected.

Best Regards,

Renaming cacti_data_query_rmon_interface_statistics.xml to the referenced file does not help, because that file is not the file supposed to be placed at <path_cacti>/resource/snmp_queries/rmon-grp1-etherstats.xml . It has a totally different structure...

Unfortunately our friend stevew forget to include the real rmon-grp1-etherstats.xml in the package...

Are you here stevew???

All of the scripts work, but you need to manually copy the attached file to <path_cacti>/resource/snmp_queries/rmon-grp1-etherstats.xml.

Errors, All/Multicast/Broadcast, and packet distribution work for me. I have not tested inBits, it is just stupid to use if you have data from the Interface MIB to plot (for example on switches).

Errors show collisions and fragments on half-duplex switch ports, which is the way half-duplex Ethernet works (these are not errors but the way of life for half-duplex), other errors are considered real errors, if you see any you should find the cause.

Packet distribution seems to be consistent also...

Feedback is welcomed,

Good work Sarge. I was a bit narked when these templates wouldn't initially work, but your mods have allowed me to import them all fine.

I have one problem with this now, and it appears to be just these templates, in that the RRD files won't create for them! Weird or what. I've added another (different) script after these, associated it with a host, and the RRD file appeared ok. I'm really not sure why they won't for this!

RRDs are created for me. In that sense even stevew's scripts are OK, just the data collector was missing.

Another extra info, consider using CACTID collector, not the PHP based one. There is a lot of data to collect, and cactid is much more efficient...

Every time I try to import these files I get the following error message:
