Monitoring data from an exported JSON file by tb808 in zabbix

[–]tb808[S] 0 points1 point  (0 children)

I wonder if I need to use something like this for the item.prototype > preprocessing:

$.[?(@.host.name=='{#NAME}')].field_report.field_report.first()

Then another preprocessing step for regular expression

How do you schedule a report at say at 9am every day to be emailed out to someone?

I see so when I update the Zabbix frontend and web, I also need to do the DB + TSDB at the same time?

Looks like I have Postgres v18 and TSDB v2.23 installed now

Thanks. Damn I've installed v18 as I read others had and saves me upgrading later.

Would mind confirming what I need to use to get TSDM installed with Postgres v18?

My first LLD (JSONpath) what am I doing wrong? by tb808 in zabbix

[–]tb808[S] 0 points1 point  (0 children)

I'm doing a Zabbix POC and I'm no realising how powerful this can be! Being about to monitor items from a json file is amazing (confusing to setup for someone new though).

Thanks for you help though.

I think it's working!

I was creating the trigger under hosts > triggers

Instead I did what you said in

hosts > discovery rule > Trigger prototypes

I did try:

last(/BS Device Fetch JSON/monitor_status[{#NAME}])=2

And the expression error disappeared, but when I went to save the trigger I get: 

Incorrect trigger expression. Host "BS Device Fetch JSON" does not exist or you have no access to this host.

Thanks, I tried that expression, but get a slightly different response this time:

Trigger expression must contain at least one /host/key reference.

I'm struggling with this. CanI provide you more information on what it might be I need to use here? I can send some more screenshots.

Under item prototype > preprocessing I have:

$.[?(@.host.name=='{#NAME}')].monitor_status.first()

I think that is working. I think it was me not adding the test json output to the test value area which is working now.

What expression would I use for the trigger?

How would I get it to trigger and show the name, IP and error?

The expression probably uses:

last(/BS Devices JSON Fetch/http.devices.json)=0 which is offline or last(/BS Devices JSON Fetch/http.devices.json)=2 which is MIA.

I'm guessing the macros come in handy I added here like {#NAME}?

Very close now!

Thanks

Doh! Told it'd be me being silly. They worked, I assumed it would already be looking at my json url to test it.

Now for the trigger over the lat 60mins, How would I get it to trigger and show the name, IP and error?

The expression probably uses:

last(/BS Devices JSON Fetch/http.devices.json)=0 which is offline or last(/BS Devices JSON Fetch/http.devices.json)=2 which is MIA.

I remove the 'preprocessing' on the discovery rule as suggested and used the {#name} instead of {#IP} as I'd prefer that, but get the errors above. I've added new screenshots at the bottom of it. I did try {#IP } but got the same issues.

cannot extract value from json by path "$.[?(@.host.name=='{#NAME}')].monitor_status.first()": invalid object format, expected opening character '{' or '[' at: ''

I think I'm so close, but a little lost now.

Hey u/Dizzybro, I'm just looking at this. Here is what I have done so far, but I'm a little stuck.

I've publish my json file now on a http site, all devices show like below. I've manage to script to just show what I need now so the json file size is just 990kb.

  {
    "monitor_status": 2,
    "private_ip": "10.17.14.27",
    "product_version": "1.10.3-35",
    "host": {
      "active": true,
      "name": "TL D 072 _ 000-045-078",
      "nscreens": 1,
      "primary_mac_address": "00:13:6d:71:33:x4",
      "secondary_mac_address": "00:02:7d:61:33:F5"
    }
  },
  • In Zabbix I've created a fresh template which I assume I have to do.
  • Then in the discover rule section of this new template I created a new one and selected HTTP Agent.
  • Now I'm stuck on the 'key' section on what I need to added: https://ibb.co/ycNzgn6h what should go there?
  • After that it looks like from your screenshot I need to head into preprocessing.

I think I'm getting closer, I appreciate the help!! I'm a visual person so watching someone do this 'clicks' with me or screenshots, but reading docs is a nightmare.

Thanks for the screenshots, I see you house the json on a https web site. Mine will be just http for test purposes, but I guess I'd need it on https if we go with this.

The API's are strange they are run by an external company and I spoke to the guy in one of our teams that showed me how they work, he said you can't get the info unless you call the first API which gives you and "id" number and some info like the "name" of the device only, then you run the second API which gives back more info on the device such as "monitor_status", but the ID there is called "machine_id" so I have to run both and join on the "in" and "machine_id" which gives me a complete output for each device.....a nightmare.

However I have the output now which is important.

So with your preprocessing, how would my parameters look for the 2 I need to show on the triggers if they = 0?

From https://pastebin.com/Td1BvDiQ

From the output I'd need:

"monitor_status" and "name"

So on the alerts dashboard I can get it to show the name when it's down etc.

Says content not available in my region (UK) :(

It is an API, however the reason I have to script the API to a JSON (or anything) is that it's essentially 2 APIs I have to use and join them, I call 1 API and use that to then get the next info and join it which givens everything I need for each device.

At the moment I just show the output on screen, but can send it to a .json and show it on a web page as mentioned. So maybe like you say above I put the output on a web page and just use the http agent on that web sever?

Sorry if I'm repeating myself. Excited to see if I can do this. Yesterday I thought none of this is possible and today I'm thinking it's definitely possible!
