PPPoE clients monitoring using interface discovery

[dziadzi]

Hello
I'm using zabbix 2.2
I want to monitor traffic on Mikrotik PPPoE interfaces.
I used network interfaces discovery, PPPoE interface is discovered and graph is automatically created.

So everything works fine, but only until client is connected. When PPPoE client disconnects, discovery rule sets particular monitored item to "Not supported" state and respective traffic graph dissapears.

In case client is disconnected, I'd want the the traffic graph to still exist and show 0 values.


I saw one posts, where somebody writes, that in Zabbix version 2.0.4 it workes like I want.

Please support
Tomasz

No ideas? No one?

I can see two ways to solve your problem:
1) Play with settings in Discovery rule , especially Keep lost resources (in days).

2) Create all PPoE interfaces manually and turn off Discovery rule.

I can see two ways to solve your problem:
1) Play with settings in Discovery rule , especially Keep lost resources (in days).

2) Create all PPoE interfaces manually and turn off Discovery rule.

1) is not a solution. "Keep lost resources period (in days)" defines how long item will be kept until removed from list. The issue here is that when discovered - item is created, supported and respective graph is available. When not discovered (client off) during the next discovery , the item gets status "Not supported" and respecitve graph is not available.
I want the graph to be not removed when related item is in "Not supported"state.

2) Considering multiple clients added each day, for sure this is not a solution.

Please help.

Found a solution. Will be fixed in 2.2.3

hi dziadzi i have same problem with you how you can fix it. when pppoe client disconnected and reconnect again, zabbix can discover the interface but cannot add the graphs because it already exist. i want to new discovered interface continue with the interface that already existed so that previous graph not gone or deleted.

There are four steps to the Discovery stage. When it completes, both peers know the PPPoE SESSION_ID and the peer's Ethernet address, which together define the PPPoE session uniquely NavyArmyCCU:

PPPoE Active Discovery Initialization (PADI)
PPPoE Active Discovery Offer (PADO)
PPPoE Active Discovery Request (PADR)
PPPoE Active Discovery Session Confirmation (PADS)
