Try to run powershell script Timeout

[frazou1]

I set a system.run command in zabbix

When the agent try to execute i always get Timeout while executing a shell script. I already increase timeout on server side at 30s and client side at 30s

2025/02/17 12:13:45.002819 [SystemRun] Executing command:'powershell -NoProfile -ExecutionPolicy Bypass -File "C:\Cortex\script\version.ps1"'
2025/02/17 12:13:49.056493 check 'system.run[powershell -NoProfile -ExecutionPolicy Bypass -File "C:\Cortex\script\version.ps1"]' is not supported: Timeout while executing a shell script.

Why use system.run for 1 specific script, better user userparameter

UserParameter=getsoftware,powershell -ExecutionPolicy bypass -File "C:\Program Files\Zabbix Agent 2\installedsoftware.ps1"

The patch to the script can be something else but you get the idea.
In this why you can use a zabbix agent (passive or active) with itemkey, getsoftware
I have many of these Userparamaters. If you have a simple script you can also use

UserParameter=stscert, powershell -c "'['Get-ChildItem -path cert:\LocalMachine\My | where {$_.Subject -like '*my app name*'} | select Thumbprint, NotAfter, Issuer | ConvertTo-json -Compress ;']'"

The ; is a newline for the powershell command.
With zabbix 7 these time-out option should work

I have the same problem, i have a script that checks ad-replications on DC's.

check_ad_replication.ps1

# Run repadmin and capture output
try {
$repadminOutput = repadmin /replsummary
} catch {
Write-Host "Failed to execute 'repadmin'. Please check if the command exists and if you have the necessary permissions."
exit
}

# Variable to keep track of the highest number of fails
$maxFails = 0

# Process each line from the output
$repadminOutput | ForEach-Object {
# Match the line containing "fails/total"
if ($_ -match "\s(\d+)\s*/\s*(\d+)") {
$fails = [int]$matches[1] # Retrieves the "fails" value

# Check if this "fails" value is higher than what we have so far
if ($fails -gt $maxFails) {
$maxFails = $fails
}
}
}

# Output the highest number of "fails"
Write-Host "$maxFails"

Zabbix agent 2 (7.4.1)
"Check 'ad.replication.status' is not supported: Timeout occurred while gathering data."

Config-file:

RefreshActiveChecks=600
Timeout=30
UserParameter=ad.replication.status, powershell -NoProfile -ExecutionPolicy Bypass -File "C:\Program Files\Zabbix Agent 2\scripts\check_ad_replication.ps1"

the same scripts works fine on others DC's running older Zabbix agent (4.4.10)

I have done some more troubleshooting and i can run the script manually from both proxy and from the host itself.

On Host

PS C:\Program Files\Zabbix Agent 2> .\zabbix_agent2.exe -t ad.replication.status
ad.replication.status [s|0]

On Proxy

mgmt-zbx-proxy:~$ zabbix_get -s [host] -k ad.replication.status
0

SOLVED!

The ITEM Timeout (in webgui) was set to 3sec (default) which was not enough for script to run and send back to zabbix-server through zabbix-proxy. Changed to 30sec and working now.
