Zabbix multiple actions on Discovery Rule

[Nortole]

Hello,

our Zabbix Server/Proxy version is 2.4.6.
I want to use a Discovery Rule for our active public IPs.

The rules configuration:
Name: IP Discovery
Discovery by proxy: true
Delay(in sec): 3600
Checks:
- HTTP / 80
- HTTPS / 443

I created 3 Actions:
1. Add IP
Conditions (AND):
- Discovery rule = IP Discovery
- Discovery status = Up

Operations:
- Add host
- Add to host groups: <groups>
- Enable host

2. Add HTTP Checks
Conditions (AND):
- Discovery rule = IP Discovery
- Discovery status = UP
- Service type <> HTTPS
- Service type = HTTP

Operations:
- Link to template HTTP

3. Add HTTPS Checks
Conditions (AND):
- Discovery rule = IP Discovery
- Discovery status = UP
- Service type = HTTPS

Operations:
- Link to template HTTPS

So here is my problem:
If the discovery detect the HTTP or HTTPS service only, the correct action is implemented ("Add IP" and "Add HTTP(S)" Checks).
If the discovery detect both HTTP and HTTPS services, only the "Add IP" and "Add HTTP" rule will apply.

That's very confusing. I thought my second rule (HTTP) only works if HTTP was discovered and not HTTPS.

I tried several conditions but nothing worked. Maybe I'm doing something wrong.

Anyone has a similar setup or an idea?

Thanks for your time and thoughts.

Hi Nortelle,

Lets take a look what happens when both HTTP and HTTPS are detected:

Conditions (AND):
- Discovery rule = IP Discovery = YES
- Discovery status = UP = YES
- Service type <> HTTPS = NO (because there are both HTTP and HTTPS)
- Service type = HTTP = YES

because AND conditions, one no is enough to fail.

3. Add HTTPS Checks

Conditions (AND): 
- Discovery rule = IP Discovery = YES
- Discovery status = UP = YES
- Service type = HTTPS = YES

Flawless!

Try adding

Service type <> HTTP to third action

Then create action Nr. 4 like

Conditions (AND)
- Discovery rule = IP Discovery
- Discovery status = UP
- Service type = HTTPS
- Service type = HTTP

Best regards,
Dmitry

Hi Dmitryb,

thanks for your fast answer.

I configured the actions as you said. And now the confusing thing I cannot explain...

My new discovered hosts got the normal HTTP template and not the HTTPS template.
The discovery rule recognized both, HTTP and HTTPS template.

Maybe you have another idea?

So currently you have this 3 actions?

Conditions (AND):
- Discovery rule = IP Discovery
- Discovery status = UP
- Service type <> HTTPS
- Service type = HTTP

Add HTTP template

Conditions (AND):
- Discovery rule = IP Discovery
- Discovery status = UP
- Service type = HTTPS
- Service type <> HTTP 

Add HTTPS template

- Discovery rule = IP Discovery
- Discovery status = UP
- Service type = HTTPS
- Service type = HTTP 

Add HTTP & HTTPS template

Discovery finds hosts with active service-type HTTP / HTTPS and both.
But only HTTP template is attaching?

[Nortole]

Yeah. This three actions plus the host adding action for new discovered hosts.

Here is a screenshot from the actions:

|Device |HTTP|HTTPS|
|1.2.3.4 | X | - |
|2.3.4.5 | - | X |
|3.4.5.6 | X | X |

1.2.3.4:
- Domain HTTP
2.3.4.5:
- Domain HTTPS
3.4.5.6:
- Domain HTTP

So this is more than a bit confusing to me.

Hello again,

Find one host, that should have HTTPS. And take a look under Monitoring -> Events (Source: Discovery)

Are you sure that you have discovered hosts with service type HTTPS?

[Nortole]

That's a good idea. I haven't looked there yet.

But unfortunately...

2016-06-16 08:37:30 1.2.3.4 example.com Host UP
2016-06-16 08:37:30 1.2.3.4 example.com Service: HTTPS UP
2016-06-16 08:37:30 1.2.3.4 example.com Service: HTTP UP

I controlled the host right now and only the HTTP template was added.

[DmitryL]

Double check that Domain - HTTP and Domain - HTTPS templates are not linked to host groups Discovered hosts and Domain hosts

[Nortole]

Oh no. I'm so sorry for this noob like question...

I found the failure.
The web checks I added with the templates had the same name... So Zabbix can't link both templates. I worked around this for hour.

Thank you very very much for your time and help!!!

Closed.

Glad to hear you solved the problem
