REST API - Delete Method not working for HostGroup

Nagios Version: 5.5.7
When i make this call through powershell, i get a HTTP 200 response from Nagios stating that it's removing the hostgroup, but the hostgroup is still there. I've toggled the applyconfig to see if that would change this, like forcing me to do a apply config but that did not change the result. Please help!
To note i have a delete method call for hosts coming from the same computer that is working successfully. Also in the Audit Log i do not see this call ever logged, but i do see the other one get logged.
The $AutoScalingGroup variable is inputted by the user who runs the script using the Read-Host command, which has the hostgroups name as a System.String (same type that is of the values in the other script i mentioned that works successfully)
Code: Select all
Invoke-WebRequest -Method Delete -Uri "https://nagios.prod02.aws.local/nagiosxi/api/v1/config/hostgroup?apikey=XXXX&pretty=1&hostgroup_name=$AutoScalingGroup&alias=HostGroup&applyconfig=1"
Here's the verbose response (I have the rest of the address chopped off for the sake of the API key. it ends with "with 0-byte payload"

Here's the output from the call when using
Invoke-WebRequest,

Could you post, or PM me your Powershell script? Also, if you could run through the script and try to remove a host group, then get a system profile from Nagios and PM that to me as well, that will help.

Your script looks great, I only changed one thing. What you had looked right, and I'm going to check to see if it's supposed to work that way, but line 15 I changed the Invoke-WebRequest inside the foreach loop to be this.
Code: Select all
Invoke-WebRequest -Method Delete -Uri "http://nagios.prod02.aws.local/nagiosxi/api/v1/config/host/${instance}?apikey=XXXX&pretty=1&applyconfig=0"
Let me know if this works on your side as well.

Thanks!
Did you happen to mean to suggest to do this with the hostgroup instead? Because the issue i'm having is only with the hostgroup API call on line 19.
When i run the command with the host name put in the suggested place in the command the output looks to prefer the placement i have in the script currently on line 15
i ran it two ways:
Code: Select all
Invoke-WebRequest -Method Delete -Uri "https://nagios.prod02.aws.local/nagiosxi/api/v1/config/host/POSTALA-95B2CB?apikey=XXXX&pretty=1&applyconfig=0"
Code: Select all
Invoke-WebRequest -Method Delete -Uri "https://nagios.prod02.aws.local/nagiosxi/api/v1/config/host/{POSTALA-95B2CB}?apikey=XXXX&pretty=1&applyconfig=0"
Here's the output:
Code: Select all
StatusCode : 200
StatusDescription : OK
Content : {
[b] "error": "Missing required variables",
"missing": [
"host_name"[/b]
]
}
RawContent : HTTP/1.1 200 OK

the way you see the host_name value is what the value looks like when entered from the $instance variable
Code: Select all
Invoke-WebRequest -Method Delete -Uri "https://nagios.prod02.aws.local/nagiosxi/api/v1/config/host?apikey=XXXX&pretty=1&host_name=POSTALA-95B2CB&applyconfig=0"
Here's the output:
Code: Select all
StatusCode : 200
StatusDescription : OK
Content : {
"success": "Removed POSTALA-95B2CB from the system. Config imported but not yet applied."
}
RawContent : HTTP/1.1 200 OK

i ran it with the hostgroup API in case that's what you meant and that didn't work either. It's still the same output as i reported originally,
i ran the code two ways:
Code: Select all
Invoke-WebRequest -Method Delete -Uri "https://nagios.prod02.aws.local/nagiosxi/api/v1/config/hostgroup/SWSIM_2019.15.6954.9533?apikey=XXXX&pretty=1&alias=HostGroup&applyconfig=0"
Code: Select all

Here's the output:

My apologies, I misread your post. When I ran the script, it had issues removing the hosts, but successfully removed the host group. What version of Powershell are you running?
Code: Select all
PS C:\> $PSVersionTable
Name Value
---- -----
PSVersion 5.1.14393.3053
PSEdition Desktop
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
BuildVersion 10.0.14393.3053
CLRVersion 4.0.30319.42000
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
Can you show me the last few entries in /usr/local/nagiosxi/var/load_url.log after you try to run the Powershell script.

No problem! I appreciate you looking into my post regardless,
Here's my current powershell version:

It looks like the file hasn't had data logged in it since last year,

Here's what it logged last:

I loaded the url in my browser and i see it's possibly related to a check or something similar that would let us know if there is a newer version? Is this correct?

Sorry about leading you astray, the DELETE methods were fixed in XI 5.6.6 I see you are running 5.5.7

No problem, i still appreciate the insight!
Are there any issues to note when upgrading versions, specifically from 5.5.* to 5.6.*? If not great, but if there's documentation on this please provide me a link to review.

Nope, should be straight forward
