User Tip: 
There is a global ping setting in UNMS options but you can overrule it for an individual device if necessary. Go to the device -> Settings -> UNMS -> 
Device specific settings and turn them ON.

Sometimes we hear questions about specific UNMS settings. In this guide, we will talk in details about the details of Ping and Outage settings.


Ping Interval


Back to Top

Firstly let's talk about how UNMS conducts a ping test with a device. There is a two-sided web socket opened between a device and UNMS and both sides are periodically checking if the connection is healthy. If they cannot see each other for a user-specified amount of time, an outage is created. Please note that the only latency that UNMS show is the one from device to UNMS though. 

Ping Address: By default, the value of this setting is your UNMS hostname. You can, however, change this address to whatever you like. If you are interested to measure your ping precisely we suggest using 'ping.ubnt.com' in this field. 

Ping interval (default): This value represents a period of time between ping attempts while a device is running normally. 

Ping interval (outage): This value represents a period of time between ping attempts while a device is reporting an outage. The idea is that a user probably wants the ping to be more frequent in case of an outage so that it is immediately apparent when the device comes back online. 


Outage Settings

This value defines a time interval after which a disconnected device is considered to be in an outage state. There are different times according to some situations as described below:

Running device reportable outage: This value represents a time interval after which a device is considered in an outage state if it was running normally before.

Restarting device reportable outage: This value represents a time interval after which a device is considered in an outage state if it was in the process of restarting before.

Upgrading device reportable outage: This value represents a time interval after which a device is considered in an outage state if it was being upgraded before.
