- Edit the existing file
- Any number of measurements can be added, but may impact performance and usability if you have too many
- Existing measurements for local CPU and memory are included
- You can measure the performance of any URL:
/api/proxy/url?url=www.example.comas the url
responseas the value
- If you want to record any other metric(s) from an API endpoint, create a new .js file in proxy as a copy of one of the existing files and include the metric(s) you want in the JSON response. The example
random_number.jsgets a random number from the remote CSRNG (https://csrng.net) site and parses the JSON response to display on the dashboard
Each measurement has the following keys:
"name": "designs94.com spark", // name of the chart "location": "board4", // location on the page "url": "/api/proxy/url?url=http://designs94.com", // url to call "value": "response", // value to get from JSON response [optional] [default: response time, ms] "chartType": "spark", // 'spark' line or 'gauge' "max": 300, // upper limit of chart [optional] [default:100] "threshold": 250, // alerting threshold [optional] [default:100] "data":  //required for chartType = spark
