Posted: Mon Sep 20, 2010 9:23 am Post subject: RMA pings over WAN instead of LAN |
|
|
Hello!
We have two geologically separated server-locations. The Hostmonitor-server is in one location and some of our servers are at the other. One of the "outside"-servers is an active RMA.
In my understanding the RMA tests the servers for what we configured and reports back to the HM.
We do however get a lot (more than 700) mails because the ping tests fail (2 of 4 packages lost) when pinging inside the LAN. We ran a manual ping-test (cmd -> ping server >> log.log) on the RMA to a server and did not find any disturbance.
Is my view wrong or what the heck is happening?
Greetings

Yes, if "Test by" test property points to some agent then test is performed by this agent.
May be you are using higher timeout for ping.exe utility so it shows better result than test item?

Hello Alex
It seems there are some discrepancies between the HM test-results and a normal ping.exe test-result.
Below you see the same four tests from the RMA to servers and the result of the HM tests of the exact same moment:
These values are not peaks. The average value is above 70ms in HM.
Can you think of any reason why that could be like that?

We tested HostMonitor, Passive RMA, Active RMA - we cannot reproduce the problem. HostMonitor shows 0ms response time for our local hosts and about 60ms when we ping google.com.
Could you please provide more information about your system?
- HostMonitor version?
- RMA version? Are you using Active RMA or Passive RMA? RMA for UNIX?
- Windows? Service Pack?
- Do you have installed some antivirus monitors, personal firewall, content monitoring software? Non stanard winsock components?
May be your HostMonitor performs a lot of tests at the same time?
Regards

HM:
version 8.68c
Windows Server 2008 R2 64-Bit
active RMA:
version 4.08
Windows Server 2008 R2 64-Bit
On both servers Microsoft Forefront is installed and the internal firewall is disabled. Between HM and RMA is a firewall appliance which routes the traffic.
We currently have 490 tests up and running.
In other news:
We just got an error on our HM-Server. The RMA manager was open and now repeatedly shows this error:
---------------------------
RMA Manager
---------------------------
Access violation at address 004CB173 in module 'rma_mgr.exe'. Read of address 00000002.
---------------------------
OK
---------------------------

Could you please try the following update: www.ks-soft.net/download/rmaman312.zip
Just unzip the file and replace rma_mgr.exe module

I replaced the manager but still the same phenomenon.
<1ms from server with ping.exe util and between 30 and 107ms in HM. |

RMA Manager has nothing to do with ping test.
New RMA Manager should fix problem that you have with RMA Manager
Regarding ping test - we cannot explain this behavior yet

Could you try to install RMA on different system?
What ping results do you see for tests performed by HostMonitor in its own LAN?
Another solution - just increase timeout a little

BTW: Are you sure you are using the same packet size for ping.exe and HostMonitor Ping test?
What packet size specified for the test? 0? Then you should check Ping/Trace option in the Options dialog. What packet size specified there?
