That's got a few security problems though. Everything is great so far, but anybody in the world with the internet access and the URL can visit my Prometheus server and see my data. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries. These lookup values should not be a frequently changing values since that might create different time series data whenever a change in any one of the label values. Prometheus Course SNMP V1 -Anyone with access to the network can poll the device data (Weaker Security). And the SNMP server running on your actual device will respond to SNMP client’s call. SNMP comprises simple Client-Server Architecture. To demonstrate this behavior I created a github repository based on vagrant inspired by the getting started guide of nomad.
