Frustration with discovery and roles

One of my frustrations with WUG is that when a device is discovered, and moved to being monitored, all it's interfaces are automatically monitored, and alerts implemented. Some devices have 200+ interfaces, and this becomes a major problem with an ongoing flurry of false positives until the devices can be put in maintenance mode, then manually 'fixed', one by one.

 

Looks like the discovery roles were updated, so now I can chose a 'switch' role, for example, and only apply a performance monitor for ping and response times. I did a single discovery of a known Cisco switch, and it worked properly. I then did a discovery group using about 15-20 IP addresses, and low and behold, all interfaces were back in the monitor list. Now, after all the unnecessary interfaces have been deleted, and only Ping Latency and Availability is enabled ... the devices stay in 'unknown status' limbo. I can right click on the devices, choose ping, and successfully get replies. Same after a 'Poll now'. If I do a 'Refresh Device Info' ... all the deleted interfaces come back ... just like they do if I do a Rescan (the latter I understand .. but refresh info should just, well ... refresh info .... not re-enable discovered interfaces).

 

Are these more bugs, or processes not worked through yet, or am I expecting something silly?

    You are correct, I did not have an active monitor set .. only the ping response time. The support tech I just talked to regarding a different issue, mentioned the same thing. up/down status is only updated by Active Monitors.

     

    I have been trying to simulate, and join, to other monitoring applications (Sitescope and Smokeping), that we are using, so we can attempt to monitor the same way. Smokeping alerts on high latency ... of which a 'no ping result' would trigger, as well. I will edit the switch role to include the active ping monitor, and just not alert on it.

     

    Thanks!

    @Dennis Hoshield​ Robbie is correct. Some additional clarification, by default Switch monitors are added via the Switch sub-role. One of the default monitors that are added is Interface active. This will scan the device and look for all interface and if there are new interface monitors from what WhatsUP Gold currently has then these monitors will get automatically added.

     

    There currently isn't a way to only add specific interface monitors as each switch that is discovered is unique. As Robbie previously replied if you disable the monitors you do not want in Device Properties we will not re-enable (However expect an option for that coming soon).

     

    As for the reason the devices are staying in unknown, it sounds from your description that you now only have Ping performance monitor (Latency and Availability) assigned and active on the device. If that is the only monitor that is assigned and active then your device will never go Up or Down, because that i determined via an active monitor. Any active monitor will work, but since you are monitoring ping performance I would recommend using the Ping Active monitor which is assigned by default.

     

    Hope this helps.

    I kind of understand on a re-scan ... but why device details? If it does it on both ... then, what is the functional difference between a re-scan and update device details?

     

    I think you might have suggested this before as well, and I forgot... if so .. sorry about that. I just have to remember to re-sort the interfaces, based on if they are enabled or not, so I'm not constantly looking at all the interfaces I don't care about. :-)

    @Dennis Hoshield​ If you delete interfaces, they will come back on a rescan and on a refresh device details. This is because we don't know if they are new or not. Your best bet for not getting them back is to use the disable option instead of deleting them.
