Metrics data is always 0

[konraddysput]

Hey!

Yesterday I tried to integrate my node application by using circonous-cip npm package and trap method. This is how my code looks like:

import * as circonus_cip from 'circonus-cip';
import * as express from 'express';
import { Logger } from '../logger/logger';
import { IMetricsOptions } from './configuration';
export class MetricsStorage {
  private readonly trap = circonus_cip.makeTrap(
    this._opts.uuid,
    this._opts.secret,
  );

  constructor(app: express.Express, private readonly _opts: IMetricsOptions) {
    if (!this._opts.secret || !this._opts.uuid) {
      Logger.getLogger().warn(
        `Metrics are disabled - undefined secret or uuid`,
      );
      return;
    }
    app.use(circonus_cip.express(this._opts.uuid, this._opts.secret));
  }
  public addMetric(name: string, value: number | string | boolean) {
    this.trap.record(name, value);
  }
}

The main issue that I have with this code is:

• I can create new metrics chart when I change metrics name which is fine
• data in each chart is always 0.

To detect problem with 0 value I used new Date().getTime() value to always have different big value. Example code:

service.metrics.addMetric('sample', new Date().getTime());

Am I doing something wrong? It seems like package contains all necessary data but circonous anyway display 0 on each chart :(

Thanks!

Look at your check bundle in the UI. If the submission URL has a host of api.circonus.com, set the opts.broker option to that and in the calls to circonus_cip.makeTrap and circonus_cip.express.

I just hit the same issue myself. I believe the issue has to do with how the _value is being formatted. For example, if we pass the value 5, it gets formatted to something like H(5e0)=1. If I hard code this value in the node_modules to just send _value as 5, Circonous does recognize the value as 5. Maybe the expectations for _value have changed since this package was updated?

hi @maier
thanks for your suggestions, but I still cannot push any data to circonous :(

Anyway if I will use wrong broker, I should be able to create new metrics chart ?

@amadden80 the first format is for histograms, sending just a number is a numeric. If you are manually enabling the metrics on in your check ensure you are setting them to be histograms.
