check ifOperStatus when gathering interfaces

[signal15]

Cacti should not gather interfaces that are administratively shutdown, as if you try to graph them, a counter with an index for that interface may not exist.

Plus, when gathering interfaces on devices that have hundreds of them, it sucks having to go through and see which ones are actually being used before making graphs for them.

This is quite easy to do. In include/snmp_functions.php add the following line before line 123:

Code: Select all

if(cacti_snmp_get($hostname, $community, ".1.3.6.1.2.1.2.2.1.7.$interface_number", "", "") != "up(1)") continue;

I don't have a chance to check if it works right now. If there are problems plase indicate them.

Actually I think cacti should collect all interfaces (even with administratively down). They should be marked as down and should be skipped later when using "Make all graphs" operation. Default cacti is prepared for this because it has unused "AdminStatus" field in internal DB.

There is no snmp_functions.php in my Cacti 0.8.6h, is this data relevant any more? I would like to be able to not produce graphs for "down" interfaces. My 196 port switch produces a lot of wasted graphs.

This is not a suggested action, as it is to specific.

Cacti indicates the state of the interface under the "create graphs for this host" under the device section.

Any interface with a status of 2 is down. You have the option to create or not create a graph per interface.
We only have cisco switches here and from what I can tell, an index does get created even if the int is in shutdown; I can't speak for other vendor devices.

I do agree with your point of having to review all the interfaces for active ones. It would be nice to have an option to "hide" inactive interfaces

Or even a "select/toggle all UP interfaces" in the Graph creation screen.
Click that button, and every interface that's up gets a check box. Then I could go through and weed out the few I don't want.
