Jason,
Thanks for your input. Your solution is a good workaround - unfortunately, that’s what it is: a workaround. To me, it doesn’t make sense to add a second ping check with different parameters. Why monitor the same item twice when, with additional “sensing” of the ping response data, you can monitor the item once and post different statuses based on that data? My issue with the current statuses are that they are black or white, good or not good, UP or DOWN. With a ping, a slow link isn’t DOWN, it’s slow. There is a gray area that Servers Alive cannot currently report on without a workaround like yours. This can also be applied to disk space checks. If you have a disk space check that reports down on “ < 1 GB” for example, SA reports it as UP even if it is at 1.000001 GB. But if it is at 999.999999 MB, it’s down. Why not have an additional status that tells me when it’s close? This is a bit more proactive. The new status shouldn’t be called LATENT because it could be applied to other check types (although all I can think of right now is disk space). Maybe the new status should be CAUTION or something similar. I look forward to your response.

A whole new status for this seems a bit unnecessary. I have a similar set up using multiple pings and dependencies. If ping1 frames received in less than 2000ms then up else down (name this one Internet) if ping2 (which depends on ping1 being up) receives frames in less than 200 ms then up else down(Name this one Internet Slow) Ping 2 would not run if ping1 is down therefore it is effectively between 200 ms and 2000ms that creates a down. So you would get a warning at 500 MS that your "internet slow is down". Even without explanation to other admins I think that is is clear that things are slow and not down. If pings take less than 200 MS then all is well. If pings take more than 2000 ms then warning will be "Internet is Down and all hell will break loose."

Right on the money Chris. -----Original Message----- From: Servers Alive Discussion List [mailto:[email protected] (mailto:[email protected])] On Behalf Of Chris Mang Sent: Monday, December 19, 2011 7:31 AM To: Servers Alive Discussion List Subject: RE: [SA-list] Latency check? Dirk, I think I know what Heath is asking for, so I'll make a "feature request". I suggest a ping response range with the ability to set the "fast" and "slow" ends of the range. If the response is received faster than the "fast" end, the item is UP. If the response is within the range, the item is "LATENT". If the response is received slower than the "slow" end, the item is DOWN. I guess this means a new status too. In your example: All frames are received in less than 200ms -> UP If one of the frames takes more than 200ms but less than 2000ms -> LATENT If one of the frames takes more than 2000ms -> DOWN Does that make sense, and would it be possible?

That's how the ping check works. For example 1 second timeout 5 frames 100% should response if one of the frames takes more then 200ms ->DOWN Dirk Bulinckx.
