Ocelot monitoring,

Ocelot monitoring,

One of the functions of the gateway is to have a unified data portal. Based on this function, we can configure monitoring on the gateway to capture and display the basic data of all web service request responses.
On the web monitoring, the general approach is to collect data and save, and then through the chart display, the database used is generally time series database Graphite, InfluxDB (https://portal.influxdata.com/downloads), OpenDSDB, etc, this article uses InfluxDB, display data generally uses a graphical framework, this article uses Grafana (https://grafana.com/get)
First, download InfluxDB and Grafana from the link above.
After InfluxDB is downloaded, as shown in figure

For more information about InfluxDB operations, see the official documentation. We will not go into details here. We only need to create a database named MetricsDB.

After grafana is downloaded, set grafana-server.exe as the Startup Program in the BINLOG.
Enter http: // localhost: 3000 in the browser, and the username and password are both admin (you can change the password after entering)
Add DataSource

Add Dashboards that can be imported using the https://grafana.com/dashboards/2125


Click Import to display the graphic view panel.

We are using the App. Metrics (https://www.app-metrics.io) package for monitoring
In the OcelotGateway project, add and reference the following five Nuget packages
App. Metrics MAIN package
App. Metrics. AspNetCore. Endpoints
App. Metrics. AspNetCore. Reporting
App. Metrics. AspNetCore. Tracking
App. Metrics. Reporting. InfluxDB

Next, start AuthenticationAPI, DemoAAPI, DemoBAPI, OcelotGateway, and TestClient. After several requests, view the monitoring page of localhost: 3000 as follows:
