Custom metrics

Camel 6 · 3:14

An integration can count something of its own, such as invoices processed, with a step in its route. The weikio CLI and the admin UI show that counter beside the integration's other figures.

Why a counter's values are fixed in the route, since each distinct value is kept as a count of its own
Publishing and deploying the change with weikio run
The counter table from weikio metrics, with its count, rate a minute and route
The Last hour line of weikio status
Opening Counters on hello's page in the admin UI, with the count, the rate a minute and a chart of the last hour

Transcript

0:01The earlier Camel videos left hello running in devtest.
0:05This video adds a step that counts hello's invoices, then reads the count with the platform's figures.
0:15hello runs in devtest on agent dev, from the hello folder.
0:19The platform already counts hello's messages,
0:22failures and memory.
0:24Your Weik.io installation keeps these as metrics.
0:28This video adds a metric you declare in the route.
0:35hello's route ends at the log step.
0:37A counter step follows it, in four new lines.
0:41The address holds three parts: the micrometer component,
0:45the kind counter that only goes up, and the name invoices.processed.
0:51Readers show the description Invoices processed beside that name.
0:55Nothing else is declared:
0:57no dependency, no installation setting.
1:01The counter takes nothing from the message,
1:03which only decides when the step runs.
1:06The store keeps a count for each set of values,
1:09so a counter opened per message runs into the store's limit.
1:17weikio run hello publishes the folder to your Weik.io installation.
1:23Ctrl-C ends the log follow, and hello keeps running.
1:27Weik.io builds the folder into a version.
1:30A version is built once, then never changes.
1:35The deployment follows latest,
1:37so the newest version is what runs now.
1:43A deployment sends figures every thirty seconds,
1:46so a new counter shows at the next send.
1:49weikio metrics sandbox/hello prints hello's figures,
1:55then its counters.
1:57The table gives the counter, its count,
2:00its rate a minute, and its route.
2:02The default window is the last hour.
2:07weikio status sandbox/hello prints the version that runs,
2:12the state, and the agent that runs it.
2:15The last hour line carries invoices.processed beside the platform's figures.
2:25Read the same figure on hello's Metrics page in the admin UI.
2:29hello's counters live under the Counters fold,
2:32whose heading names this one.
2:34The window is the last hour.
2:36A click opens the fold.
2:39The opened row runs from the counter and its description to the count,
2:43the rate, a chart and the route hello.
2:50hello counts the invoices it handles, from the last lines of its route.
2:55The counter lives in Weik.io, kept with hello's other figures.
2:59Two readers reach the same figure, the Weik.io CLI and the admin UI.
