need a special config.

[binaer]

Hello community

I need a special community. We're running an SMTP-Cluster. Time by time, one of the backend-server's overloaded (which is desired and okay and can happen - so, everything is fine). BUT: we would like to isolate this one sub-server from the cluster (scripts are ready to use).

Now, I need the following configuration:
1. Test: shows "Server overload".
2. Test: should fire ONE command (either SSH-Logon and fire a command with parms, or should fire a bat-file - but I NEED TO HAVE the output of this script checked by HM).

1. Question:
How should I configure my test (which one should I use?) that it is only triggered by another host and NOT repeat checking (the 2. Test should only run when the 1. Test changes status).
2. Question:
How can I check the Return-Codes (scriptres:OK or scriptres:Bad) and alert within the 2. Test?

I know, I could just add the "action" in the first test, but I really need the scriptres-Result being checked by HostMonitor (hence the fact that we have more than one server in the cluster and therefore, more than one can be isolated - but only all-1. So, if the last server is also overloaded, we would have a serious problem and therefore cannot just isolate this last one as well). Our Bash-Script is testing everything and just reports the status "scriptres:OK or scriptres:Bad" back...

I hope, I was clear enough... yes, it is a special test case but it is exactly, what we need

kind regards
Pascal

which one should I use?

It depend on how do you determine that Server is overloaded.
It can be CPU Usage test or Dominant process or SMTP,etc.

1. Question:
How should I configure my test (which one should I use?)
that it is only triggered by another host and NOT repeat checking (the 2. Test should only run when the 1. Test changes status).

"2. Test" should be disabled.
"1. Test" may start Bad action "Run HMS script" with two commands:
EnableTest "2. Test"
RefreshTest "2. Test"

"2. Test" should start "Run HMS script" action (for Bad and Good status) with the following HMS script:
DisableTestByID %TestID%

2. Question:
How can I check the Return-Codes (scriptres:OK or scriptres:Bad) and alert within the 2. Test?

You may use ShellScript test with the following settings:
Start CMD: cmd /c %Script% %Params%
Script (Example):

Code: Select all

@echo off
echo scriptRes:Ok:My Script Reply

Script should echo using the following format: ScriptRes:<TEST_STATUS>:<TEST_REPLY>
E.G.
ScriptRes:Unknown:My Reply
ScriptRes:Ok:My Reply
ScriptRes:Bad:My Reply

"2. Test" should be disabled.
"1. Test" may start Bad action "Run HMS script" with two commands:
EnableTest "2. Test"
RefreshTest "2. Test"

great, did that, thank you. Now an additional Question: can I parse something like the trigger test-name to the hms-script so that I don't have to make one script for each backend-host?

"2. Test" should start "Run HMS script" action (for Bad and Good status) with the following HMS script:
DisableTestByID %TestID%

did that, thank you.

You may add test name("2. Test") to Comment line (e.g. Comment line 3) field of "1. Test" and modify HMS script:
EnableTest %CommentLine3%
RefreshTest %CommentLine3%

thank you - I'm trying to implement this right now and will give you feedback soon.

hmm, now, when I try to execute the bat-file, I'm getting as a reply to HostMonitor:

Unable to read from standard input: The handle is invalid.

But the script seems to run fine - and if I execute it from the command line, it works without any Problem (gives me back:)


any idea?

scriptres:OK:Server not disabled (smtpsrvX)

(this "Server not disabled" is okay in that case...)

just found this:
http://www.ks-soft.net/cgi-bin/phpBB/vi ... le+invalid

I have a Shell Script defined
Start cmd: %Script% %Params%
Script: "C:\Program Files (x86)\HostMonitor\Scripts\smtpsrv\isolate.bat" %1 %2
Params: stop smtpsrvX

Gives me the above error.

Could you try to add/modify "SScript_UseWindowsPipe=0" line in [Misc] section of hostmon.ini file and restart HostMonitor?

Yes, didn't help in that case. Any other hint would be appreciated

Now, I can't start HostMonitor anymore using the Service-Section in Windows SRV (2008, 64 bit), Error 193, 0xc01
I can start it manually... I might do that as I don't want to reboot the server right now...

It keeps dying, even with the 9.5-Version... except if I open it manually (not use the "service"-Function (also, not use the /service-Parm)

In the system log, I can find: "is not a valid W32-Process"...

this is absolutely weird... I could solve this issue. There was a file in the "C:/"-Root, called "Program". It prevented me to start the service. The file got placed there when I shut down HostMonitor (but it doesn't look like it's a HM-Issue!). I'm just writing it down here so that in case it happens to someone else, he's able to solve it. Even: my root problem is not solved, but it's not urgent.

Do you mean HostMonitor service does not start when there is "c:\program" file on the disk?
HostMonitor does not create such file (unless you setup c:\program as target for some log or report file or use some custom script).

Do you mean "Unable to read from standard input: The handle is invalid." error?

exactly. Yes, I didn't mean to blame this on HostMon-Software... it looks like a Windows-Problem. Just wanted to write it down how to solve for others.

Do you mean "Unable to read from standard input: The handle is invalid." error?

yes, right. I'm still facing the same issue. Workaround doesn't seem to work, not even switching to "SSH Test"-Method (see http://www.ks-soft.net/cgi-bin/phpBB/vi ... php?t=5311). Any other idea?
my hostmon.ini [Misc] section:

Code: Select all

[Misc]
[...]
SScript_UseWindowsPipe=0

I'm running the 9.50 version now (didn't help - from 8.80).

I have a Shell Script defined
Start cmd: %Script% %Params%
Script: "C:\Program Files (x86)\HostMonitor\Scripts\smtpsrv\isolate.bat" %1 %2
Params: stop smtpsrvX

This cannot be executed. BAT file is not executable file.
Should be
Start cmd: cmd /c "C:\Program Files (x86)\HostMonitor\Scripts\smtpsrv\isolate.bat" %Params%
Script: <empty>
Params: stop smtpsrvX [/quote]

thank you - but doesn't make any difference

HostMonitor started as service? Application? Acount used to run HostMonitor?
UAC enabled?
Service Pack?
Antivirus monitor?

Hey.

Started as service? Yes
Account used? System Account
UAC enabled. Disabling it needs reboot, I think.
Windows Server 2008, R2 Standard, SP1, 64-bit
no AntiVirus on this Machine

Account used? System Account

Local system account is specified on Windows Services applet (services.msc) and on Service page of HostMonitor Options dialog, right ?
