Telegraf: Takes the output of the Python script as an input and translates it to Prometheus.Parsing raw text output into structured data NTC Template which is a TextFSM template for. In this post we have the following components being used:Ĭommand output, and leverage the corresponding NTC Template Prometheus_client library check out their Github Wanted to keep the Python execution as simple as possible. Possible to remove the requirement for Telegraf and have Python create the Prometheus Metrics. This data will then get transformed by Telegraf into an output that is usable by Prometheus. $ python3 asa_anyconnect_to_telegraf.py -host 10.250.0.63Īsa connected_users =1i,anyconnect_licenses =2i If executing just the Python script without being executed by Telegraf, this is what you would see: In this you will see that you can get custom metrics into a monitoring solution without An SNMP query would be quicker than using SSH and getting data if you want basicĬounts. Grafana: Solution to build dashboards, natively support Prometheus toĪn alternative to creating this Python script, you could have looked at using the Telegraf SNMP.Over HTTP, stores it, and exposes an API to query the data Prometheus: Time Series DataBase (TSDB).OUTPUT: Expose the data over HTTP in a format compatible with Prometheus.INPUT: Execute the Python script every 60s and read the results from stdout.Multiple plugins to ingest data and that can send data to many databases out there. This is presented via stdout in Influx data format Python: Collects information from the device via CLI and gets structured data by using a NEW.Users will connect to the ASA for remote access VPN services. Here is what the data flow will look like: The approach would work on other network devices, not just Cisco ASAs.Ĭonsidering the recent demand for ASA information, we will use this as an example. Quickly collect information from your Cisco ASA firewall leveraging The visibiility and monitoring of their VPN infrastructure. With many people being asked to work from home, we have heard several customers looking to enhance
