I don't need a 'visual' tool, although graphical representations of data sets are usually useful. I'm looking for *any* tool that will do the job reasonably.
Pinging will not help solve the issue I'm looking for. It is my understanding that a ping and response would both be dropped during the outage time. So, to know the full duration of the outage / the network repair time, a successful ping would have to happen immediately before and immediately after the outage. In order to get 1ms resolution, you would need to be pinging 1000 times per second (if you sent a ping the moment before an outage, the reply would be dropped... and if you sent it a moment afterward, the request would be dropped). It sounds like... the tool I'm asking about doesn't exist. Also, it sounds like nobody actually tests / measures their recovery time. ------------------------------ On Mon, Jan 29, 2018 at 10:45 AM, Faisal Imtiaz <[email protected]> wrote: > If you are looking for a 'visual' tool, then look at pingplotter ... > > Regards. > > Faisal Imtiaz > Snappy Internet & Telecom > http://www.snappytelecom.net > > Tel: 305 663 5518 x 232 <(305)%20663-5518> > > Help-desk: (305)663-5518 <(305)%20663-5518> Option 2 or Email: > [email protected] > > ------------------------------ > > *From: *"Christopher Gray" <[email protected]> > *To: *[email protected] > *Sent: *Monday, January 29, 2018 10:06:59 AM > *Subject: *Re: [AFMUG] Failover / Recovery Time Testing? > > I want to use a tool that will time the "outage" automatically. > For example, switches with ERPS capability usually claim things like "sub > 50ms recovery".
