Clear Alarms on all hosts in a cluster - PowerCLI

[aculed]

Can someone please provide an example of how to make use of the new ESXi 6.7 API function ClearTriggeredAlarms as described here: https://vdc-repo.vmware.com/vmwb-repository/dcr-public/3325c370-b58c-4799-99ff-58ae3baac1bd/45789cc5-aba1-48bc-a320-5e35142b50af/doc/vim.alarm.AlarmManager.html

Currently, I'm acknowledging alarms on all hosts within a cluster in a script, but I'd like to take that a step further and clear that specific alarm on all hosts as well.  I can't seem to get the filter right to do this appropriately.

Thanks!

Try something like this.
Note that you can specify different values for all three enums, depending on which alarms you want to clear.

$alarmMgr = Get-View AlarmManager

$filter = New-Object VMware.Vim.AlarmFilterSpec

$filter.Status += [VMware.Vim.ManagedEntityStatus]::red

$filter.TypeEntity = [VMware.Vim.AlarmFilterSpecAlarmTypeByEntity]::entityTypeVm

$filter.TypeTrigger = [vmware.vim.AlarmFilterSpecAlarmTypeByTrigger]::triggerTypeEvent

$alarmMgr.ClearTriggeredAlarms($filter)

I know this is an old thread but is there a way to filter based on date?

Scenario: 

1. reset all alerts
2. currently active one retriggers.
3. tech is called for an already existing alert issue (host down or something like that). 

Would be nice to filter based on date and only reset the older triggered alarms.   

Could you filter based on acknowledged alerts and only clear those?  Then possibly use another method to acknowledge the older alerts and then clear only the acknowledged alerts with this method?

 

 

This is the original solution posted by LucD which works great for clearing all triggered alarms. 

Note that you can specify different values for all three enums, depending on which alarms you want to clear.

 

$alarmMgr = Get-View AlarmManager

 

$filter = New-Object VMware.Vim.AlarmFilterSpec

$filter.Status += [VMware.Vim.ManagedEntityStatus]::red

$filter.TypeEntity = [VMware.Vim.AlarmFilterSpecAlarmTypeByEntity]::entityTypeVm

$filter.TypeTrigger = [vmware.vim.AlarmFilterSpecAlarmTypeByTrigger]::triggerTypeEvent

$alarmMgr.ClearTriggeredAlarms($filter)

Afaik, this is still the only method that clears all alarms.

No option to clear a specific alarm.

[LucD]

Btw, this methods is for all alarms in a vCenter, there is no option afaik, to only clear alarms in a specific cluster with this method.

[aculed]

Thank you for your help as always.  Can I use the TypeTrigger to filter on a specific vC alarm?  I worry about your last point that this is clears across the entire vC

[LucD]

I'm afraid not, the AlarmFilterSpecAlarmTypeByTrigger enum only has three values: All, Event and Metric.

The AlarmFilterSpecAlarmTypeByEntity enum also has three possibilities: All, VM and Host.
Add to that the status which takes a value from the ManagedEntityStatus enum: gray, green, red and yellow.s.

You have some limited filtering possibilities.

For example: all red alarms for ESXi nodes that are triggered by an event.

[aculed]

That's what I was afraid of.  Thank you again!

That is a rather old version.
I suggest you upgrade first.
See Welcome PowerCLI to the PowerShell Gallery - Install Process Updates - VMware PowerCLI Blog

Hi LucD,

As you suggested, i upgraded and its running without any error but alerts are not resetting green.

PS C:\Users\RachappaChalmi\Documents\Scripts> .\AlarmTestvCenter.ps1
PS C:\Users\RachappaChalmi\Documents\Scripts> .\AlarmTestvCenter.ps1
PS C:\Users\RachappaChalmi\Documents\Scripts> .\AlarmTestvCenter.ps1
PS C:\Users\RachappaChalmi\Documents\Scripts>

Below is the script you shared, i just put this in notepad and made it .ps1 and ran it. but alerts are not resetting

$alarmMgr = Get-View AlarmManager
$filter = New-Object VMware.Vim.AlarmFilterSpec
$filter.Status += [VMware.Vim.ManagedEntityStatus]::red
$filter.TypeEntity = [VMware.Vim.AlarmFilterSpecAlarmTypeByEntity]::entityTypeAll
$filter.TypeTrigger = [vmware.vim.AlarmFilterSpecAlarmTypeByTrigger]::triggerTypeAll

$alarmMgr.ClearTriggeredAlarms($filter)

This is a method that was introduced in 6.7.
You are on 6.7 or higher I assume?

[LucD]

I mean the vSphere version 6.7

[rachappachalmi]

yes, vCenter 6.7

[LucD]

Just tested again, works perfectly for me.

If your alarms have the Yellow status, you could add that option

$alarmMgr = Get-View AlarmManager
$filter = New-Object VMware.Vim.AlarmFilterSpec
$filter.Status = [VMware.Vim.ManagedEntityStatus]::red,[VMware.Vim.ManagedEntityStatus]::yellow
$filter.TypeEntity = [VMware.Vim.AlarmFilterSpecAlarmTypeByEntity]::entityTypeAll
$filter.TypeTrigger = [vmware.vim.AlarmFilterSpecAlarmTypeByTrigger]::triggerTypeAll

$alarmMgr.ClearTriggeredAlarms($filter)

[rachappachalmi]

Thanks a lot LucD !! 

As always you helped and its working fine now for me

Thanks a again !!

[JAVUS]

I would like to know if there is a way to reset to green for specific alarm to only a VM , I want to attach a script to alarm

[LucD]

Afaik unfortunately no.
