open-hardware-monitor-zabbix-query Learn more about Zabbix on the official website. You might be thinking — what the hell is that monstrous formula? Community templates: share. Luckily, we can create that metric using vmware. I know this is a very old thread but open hardware monitor zabbix query it was helpful for me I'll post a quick improvement. Create a trigger for datastore utilization — step 2. Autodiscovery Autodetect monitr devices.

With the Zabbix agent, you can monitor virtually anything at the OS level. Check out this step-by-step Linux and Windows server monitoring guide. Severity can be whatever you prefer. Keep in mind that we have created a trigger prototype on the template so it could take up to an hour for Zabbix to create the actual triggers on the host. What if you want to change the alarm threshold only for some specific datastore? Is it possible? Of course, everything is possible with Zabbix, we just need to use user macros with context.

However, we are planning to use that macro in the LLD trigger prototype where datastore is not known until Zabbix creates the trigger. Next, go back to the trigger prototype that we previously created and replace the number 5 with our macro so that the trigger name becomes:. Well done! Nothing much has changed except that Zabbix will now use that macro in triggers instead of number 5. However, we can now use context macros and change the alarm threshold only for some datastores.

You can add as many context macros as you want or use regex t o match multiple datastores. It is not clear to me why the Zabbix team did not include an item that shows the remaining free space on the datastore in bytes.

We have only in percentage in the official template. Who knows, maybe they will add it later in some release. In the meantime, we can easily add that item. Keep in mind that we have created a item prototype on the template so it could take up to an hour for Zabbix to create Open Hardware Monitor Zabbix Test the actual items on the host. By default, the official Zabbix template for VMware does not include any graphs, so to view datastore performances you will need to use ad-hoc graphs from the latest data tool.

However you can easly update the official templates and add custom graphs. In this step, we will create utilization and latency graphs for all the datastores using the graph prototype option. With those graphs, you can analyze datastore performances and manage capacity planning for them. Now that you know how to prototype graphs, you can create others in a similar way.

Here is just one example of a graph configuration for datastore latency statistics:. Keep in mind that we have created a graph prototype on the template so it could take up to an hour for Zabbix to create the actual graphs on the host. There is an article on the Zabbix blog where you can learn about trend prediction, so I will spare you the theory. Here, I want to focus on practical work. Trend prediction can be configured in triggers and in calculated items, I will use the latter.

All you need to do is to create a prototype item just like before but with parameters like in the picture below:. And remember, you have created an item prototype on the template so it could take up to an hour for Zabbix to create the actual items on the host. You might be thinking — what the hell is that monstrous formula?

Well, yes and no. I think I owe you a little clarification of that complicated formula. Zabbix official documentation demonstrates how to use timeleft function:. However, in another document Zabbix states that additional calculations are necessary for prediction to be reliable. In short, Zabbix has to check multiple time periods to keep up with rapid changes that may occur in resource usage datastores. In our formula, Zabbix will make a prediction using various periods 8h, 4h, 1h, 15m and will take into account the worst prediction.

If the prediction goes beyond 3 years, Zabbix will set prediction to 3 years i. Now you can combine everything you have learn in this tutorial so far and create this wonderful trigger:. As you can see, the trigger name is full of macros. As for the trigger expression, the first condition in the trigger expression is unchanged. Zabbix did not include an item that shows the percentage of CPU usage of the hypervisor host.

No problem, we can easily add that item using Zabbix key called vmware. Note that there is another option if you cannot get the data about CPU percentage using the key vmware.

You can create it just like on the hypervisor template, but with a different key, use vmware. We are also missing an item for memory utilization in percentage in the official Zabbix VMware template.

Zabbix documentation defines this metric as the time that the virtual machine was ready, but could not get scheduled to run on the physical CPU during last measurement interval. In other words, you can detect overprovisioned or underutilized hypervisors and plan virtual machines VM management accordingly. Luckily, we can create that metric using vmware. I encourage you to explore additional performance metrics using Zabbix vmware. Also, make sure that you restart the Zabbix server after updating the configuration.

Also, upgrading Zabbix to the latest version may help. Since the Zabbix 5. Make sure that those macros are configured correctly. Thank you for reading. Now, that you have your VMware monitored, you can setup Zabbix email notifications and escalations! Zabbix 5 Dashboard. VMware architecture. Last edited by captainmac40 ; , Reason: Adding files.

Template As you request , here is the template with auto-discovery , item for the sensors and an simple graph.

Enjoy and please feedback Once again thanks! Thank you! Thank you very much for this great Template, works very good. So now I can monitor temp of my gaming pc. I know this is a very old thread but since it was helpful for me I'll post a quick improvement. My system was having collisions with the temporary files being made by the powershell scripts so I removed the need for them. Yes No.
