add_graph.php -> more than one snmp-field and regexp

[killshoot]

Hi,

I use cacti in a large deployment (~3500 devices, 75k graphs).

I've customized some cacti code to add each night a graph for the new interfaces that come up (--snmp-field=ifOperStatus --snmp-value=Up).

My problem is with that I add lot (50k!!!) of not wanted interfaces (vlan, subinterface, console etc), that I need to delete with another script.

Is it possible to add the possibility to do a regexp to the "ifType" or "ifAlias" so I can add only ethernet or gigabitethernet interface?

Thus the string to add graph will be like this :
add_graphs.php --host-id=2713 --graph-type=ds --graph-template-id=2 --snmp-query-id=1 --snmp-query-type-id=13 --snmp-field=ifOperStatus --snmp-value=Up --snmp-field_regexp=ifType --snmp-value_regexp=ethernet

I think this feature will be very useful for large deployment.

Best regards,

Vince

I've coded this feature now!

http://bugs.cacti.net/view.php?id=1396

I've code a first draft (an update of add_graphs.php). I'm a network guy, not a core programmer thus be indulgent

I've tested this script on my cacti lab creating ~18k graphs on around 880 devices without issue.

I hope this feature will interest you.

Best regards,

Vincent Kilchoer aka Big Vi

Exemple : with this line I can create graphs for all up interface with Iftype containing "ethernet" for host-id 2713 :

Code: Select all

add_graphs.php --host-id=2713 --graph-type=ds --graph-template-id=2 --snmp-query-id=1 --snmp-query-type-id=13 --snmp-field=ifOperStatus --snmp-value=Up --snmp-field_regexp=ifType --snmp-value_regexp=ethernet

Appreciated!
But to to current works, this will not be covered asap.
But for next release, I surely will consider it

Did you open a feature request in Mantis?

Hello,

I used the following command to add "interface-Unicast Packets" template to each interface on a device

php add_graphs.php --host-id=365 --graph-type=ds --graph-template-id=23 --snmp-query-id=1 --snmp-query-type-id=13 --snmp-field=ifOperStatus --snmp-value=Up

The following output is obtained

Graph Added - graph-id: (21999) - data-source-ids: (22914, 22914)
Graph Added - graph-id: (22000) - data-source-ids: (22915, 22915)

But the problem is that there is interfaces are not being graphed, as show in the image below..

by turning on the Graph debug mode for one of the interface the following error is shown

Please select the link given in my very first post at that thread.
It will take you to the official plugin repository, wre you will find everything, including documentation. And there you'll find the download file as well.

Thanks for that,

i have another issue, when i run

patch -p1 -N --dry-run < plugins/autom8/cli.patch

the following error is obtained

can't find file to patch at input line 4
Perhaps you used the wrong -p or --strip option?

I am not sure what this error is or how to go about fixing it.

Also do you think it will be wise for me to make a backup of the current working piece of cacti just in case i cannot configure this plugin properly, to avoid loosing what i have working already.


thanks

Enter
cli/add_graph_template.php
to that question
