Assistance with building a network operations dashboard using Telegraf and Grafana

I have a basic Grafana site that's working, pulling data from a number of switches and routers. It displays the in/out graphs fine but I'm struggling with polling error rates getting an error count dashboard. I want a heatmap dashboard or similar with the ability to change colour based on thresholds of error and port usage. The indicidial cells of the map should then link to mode detailed graphs / dashboards beneath. I need someone that understands SNMP on cisco devices and who also knows telegraf well and can filter the large volume of data that is pulled to lower the load on the system. You would not have direct access to the server, I would have to run a session with you controlling my PC. I have webex etc. for this purpose. If this corresponds to your skillset and you have time today, please get in touch. Thanks, Daniel
