Hashtag preventing graph Explorer graphs from loading

meganwilliford · Post by **meganwilliford** » Fri Jun 11, 2021 3:55 pm

Hello,

I think I've gotten to the bottom of why the multistacked performance graphs will not load for some hosts but I have no idea how to get around it.

We use a # as an indicator in the host name of some of the hosts we monitor. Come to find out, I think it is preventing multistacked performance data to load. This is not an issue with the normal performance graphs, only the graphs in the graph explorer.

The hosts are collecting and are reporting performance data, it just will not load in the graph explorer. Is there a way to get it to load while keeping the # in front of the server name?

I've attached two pictures with what I'm talking about. Same server is used in both examples. First example the # exists before the host name. Second example I removed the # and the data populates.

Hi,

Go to Configure, Core Config Manager. click on Hosts, and then change the "Host Name" field:

Save it, Apply Configuration.

Please let me know how things turn out.

Thanks

Hi, we use # as an indicator. It is intentionally in front of the host name and do not want to remove it from the host name. Is there a way to get the performance data to load while keeping the # in front of the host name?

Hi,

There isn't a way to get the host performance data with a leading "#".

Could you use some other indicator? I jut tried _#hostname and it looks like it works.

Could you tell me how you are using it as an indicator in case there is already some functionality
that can do this?

Thanks

We have a ServiceNow integration set up to ingest the objects/statehistory api data and process into events. There are some scenarios we don't want ServiceNow to process events for. There is a rule on the ServiceNow side to ignore host events with a # in front. Is there a way to optionally ignore objects/statehistory data? We had no luck, hence the #.

Hi,

I think I found a way!

If you want a host ignored put something in the alias field, say "no servicenow"

Now in your API request add "customvars=1"

Code: Select all

 curl -XGET "http://192.168.23.82/nagiosxi/api/v1/objects/servicestatus?apikey=224nEJb8u3ANILBsvlSpnr6fa0JhdVAj5lLfgFkUbrNcAOCWiUri8Nm9L0ceSVin&customvars=1&pretty=1

"

The result is something like:

Code: Select all

        },
        {
            "host_name": "192.168.23.81",
            "service_description": "ens160 Bandwidth - Outbound",
            "display_name": "ens160 Bandwidth - Outbound",
            "host_object_id": "193",
            "host_address": "192.168.23.81",
            "host_alias": "no servicenow",
            "icon_image": "",
            "icon_image_alt": "",
            "notes": "",

Now instead of keying off the host name, have servicenow look at the alias field to decide if it should
process the event.

Please let me know how this works for you.

Thanks

This looks like a bug.

# is not listed in the illegal object name chars so it should be available for use:

Code: Select all

illegal_object_name_chars=`~!$%^&*|'"<>?,()=

Please edit this file:

Code: Select all

/usr/local/nagiosxi/html/includes/components/graphexplorer/graphexplorer.js

Change this (around line 88):

Code: Select all

        host = v.host.replace(/ /g, "_");
        service = v.service.replace(/ /g, "_");

To this:

Code: Select all

        host = encodeURIComponent(v.host.replace(/ /g, "_"));
        service = encodeURIComponent(v.service.replace(/ /g, "_"));

Then clear your browser cache or try to shift+reload the web page and let us know if that resolves your issue.

@gsmith, thanks so much for the alias tip! We will definitely explore using that option in the future.

In the meantime, the trick @ssax gave worked like a charm!

I really really appreciate your help.
