If I land a project using Zabbix again, one of the things I need to look into is [WayBack] Best android apps for zabbix – AndroidMeta.

This is a small reminder to myself that when monitoring Windows service memory consumption from Zabbix and you get zeros, it means you need to monitor the Windows process instead of the service. The process will give you actual memory usage.

If the Zabbix configuration on Windows (especially mismatches in C:\zabbix\zabbix.agentd.conf.d), then the Zabbix Agent will not start at all:
C:\zabbix\bin\win64>zabbix_agentd.exe --start
zabbix_agentd.exe [4711]: ERROR: cannot start service [Zabbix Agent]: [0x0000041D] The service did not respond to the start or control request in a timely fashion.
This is how to check it before starting the service:
C:\zabbix\bin\win64\zabbix_agentd.exe --config C:\zabbix_agentd.conf
zabbix_agentd.exe [43]: ERROR: cannot add user parameter "MyDuplicate[*],PowerShell.exe -File C:\zabbix\UniquePowerShellScript.ps1 "$1"": key "MyDuplicate" already exists
The problem is that in the C:\zabbix\zabbix.agent.conf.d directory, two files had a similar config:
UserParameter=MyDuplicate[*],PowerShell.exe -File C:\zabbix\FirstPowerShellScript.ps1 "$1"
UserParameter=MyDuplicate[*],PowerShell.exe -File C:\zabbix\SecondPowerShellScript.ps1 "$1"
The problem is that the first part of UserParameter (before the [*]) is a key which needs to be unique over all configuration files.
If everything is fine, you will see this:
C:\zabbix\bin\win64\zabbix_agentd.exe --config C:\zabbix_agentd.conf
zabbix_agentd.exe [1581]: use foreground option to run Zabbix agent as console application
If you need to manually start Zabbix as a service, then perform this (the first step is not needed if the service has already been stopped):
C:\zabbix\bin\win64>zabbix_agentd.exe --stop
zabbix_agentd.exe [1642]: service [Zabbix Agent] stopped successfully
C:\zabbix\bin\win64>zabbix_agentd.exe --start
zabbix_agentd.exe [1642]: service [Zabbix Agent] started successfully

The [WayBack] stock zabbix_agentd.conf is about 10k and the documentation quite a bit larger, so it can take a while to figure out a setting.
I needed one to ensure that scripts could take longer to execute than the default.
Searching for a per-script setting on the server side revealed no solution, so I had to solve it on the agent side. There, a per-script setting is also impossible: there is only the global Timeout (one word, no PascalCase like TimeOut) setting in zabbix_agentd.conf which is the same for Unix and Windows based Zabbix installations:
Unix: [WayBack] Zabbix Documentation 3.0 – 3 Zabbix agent (UNIX)
Parameter Mandatory Range Default Description Timeoutno 1–303Spend no more than Timeoutseconds on processing
Windows: [WayBack] Zabbix Documentation 3.0 – 9.4 Zabbix agent (Windows)
Parameter Mandatory Range Default Description Timeoutno 1–303Spend no more than Timeoutseconds on processing
In my case it was for a PowerShell script that ran twice a day to verify how recent the installations on a particular machine were. The Timeout value needed to be at least 15 for that:
### Option: Timeout
# Spend no more than Timeout seconds on processing.
#
# Mandatory: no
# Range: 1-30
# Default:
# Timeout=3
Timeout=15

A few notes on Zabbix triggers and web scenarios:
For now I’ve set these kinds of triggers on response times:
Warning: 2 minute of response time > averageAverage: 5 minutes of response time > 2*averageHigh: 10 minutes of response time > 4*avarageDisaster: 30 minutes of response time > 10*averageThese are the colours by default used for the trigger levels: at http://example.org/zabbix/adm.triggerseverities.php
Default Zabbix trigger severities and their colours.

When you look at the “Response time” graph for a Zabbix web scenario step that fetches a URL, you’d think the unit would be milliseconds (as last/min/avg/max are all listed in milliseconds).
However an expression like this puts the trigger off the scale:
{owa.example.org:web.test.time[https OWA,https OWA returns http code 200,resp].last()}>100
This trigger however works:
{owa.example.org:web.test.time[https OWA,https OWA returns http code 200,resp].last()}>0.1
The [WayBack] web scenario step items topic indeed lists the web.test.time unit as seconds
–jeroen
Web scenario:
https OWA returns http code 200 15 sec https://example.org/owa
Trigger:
0.1″ class=”size-medium” /> {owa.example.org:web.test.time[https OWA,https OWA returns http code 200,resp].last()}>0.1

I’m monitoring quite a bunch of Windows machines with Zabbix.
One of the services I turn off for monitoring is ShellHWDetection as otherwise you get this notification often:
Service "ShellHWDetection" (Shell Hardware Detection) is not running (startup type automatic)
When it happens, it’s always when there is nobody logged on to the machine. But sometimes you do not get this message. I’ve not fully figured out the pattern well, but since the service is associated with auto-play of inserted CD/DVD/USB and other media, I don’t bother too much.

Like any product documentation, Zabbix’ is shattered and terse.
So here is how I ensured a specific user could edit the items of hosts:
- Added new user group named
Administer Configuration Host Itemscontaining userExamplehaving these read-write composing permissions:
- Applicatie ontwikkel test
- Applicatie productie Approve demo VPN
- servers Dbases Kantoor applicaties
- Changed
User typeof user namedExamplefromZabbix UsertoZabbix Adminso access to theConfigurationtab is granted.See 2 Permissions [Zabbix Documentation 3.0] for
User typeexplanation; excerpt:
Zabbix Admin: The user has access to the Monitoring and Configuration menus. The user has no access to any host groups by default. Any permissions to host groups must be explicitly given.

The default [WayBack] Zabbix Disk space usage graph (named Disk space usage {#FSNAME}) for Windows looks like this:
Total disk space on C:
What I want is a graph over time. Based on that, I can start working on different triggers than the default “less than 20% free space available“, for instance:
So I want graphs similar to the CPU load (in the graph itself called Processor load) graph which looks like this:
CPU load (a.k.a. Processor load) is actually graphed “over time”
It is part of the Graph prototypes for the Template OS Windows discovery list Mounted filesystem discovery:
For now I’ve added this graph prototype as Line chart with 95th percentile:
If that work, I can start working on the triggers:
