Locating Time-Series Data in Prometheus

Prometheus allows you to collect a wide variety of metric data in one location. It also provides useful tools for exploring and querying your data. In this lab, you will have the opportunity to perform some very basic queries to obtain some data from a Prometheus server. You will obtain the current value of a metric, and you will also look up a set of multiple time-series values for that metric.

Challenge

Get the Current Temperature of the Data Center
1. In a browser, access the Prometheus expression browser:
  
  http://<PROMETHEUS_SERVER_PUBLIC_IP>:9090
2. Run a query to obtain the current datacenter_temp:
  
  datacenter_temp
3. Copy the current temperature value.
4. Log in to the Prometheus server and open the file that will contain the temperature data:
  
  vi /home/cloud_user/current_temp.txt
5. Enter or paste in the current temperature value obtained from the Prometheus expression browser, and then save the file.
Challenge

Get All Time-Series Entries for the Data Center Temperature Over the Last Five Minutes
1. In the Prometheus expression browser, run a query to obtain the data:
  
  datacenter_temp[5m]
2. Copy all the values (including the timestamps).
3. Return to the Prometheus server terminal and open the file that will contain the data:
  
  vi /home/cloud_user/5_minute_temp.txt
4. Paste in the time-series data obtained from the Prometheus expression browser, and save the file.
