ClickUp Observability

Overview

Monitor ClickUp API v2 integrations with metrics (request rate, latency, errors, rate limit usage), distributed tracing, and alerting.

Key Metrics

Metric	Type	Labels	Description
`clickup_requests_total`	Counter	method, endpoint, status	Total API requests
`clickup_request_duration_seconds`	Histogram	method, endpoint	Request latency
`clickup_errors_total`	Counter	status_code, error_type	Errors by type
`clickup_rate_limit_remaining`	Gauge	token_hash	Rate limit headroom
`clickup_rate_limit_resets_total`	Counter		Times we hit 429

Prometheus Instrumentation

import { Registry, Counter, Histogram, Gauge } from 'prom-client';

const registry = new Registry();

const requestCounter = new Counter({
  name: 'clickup_requests_total',
  help: 'Total ClickUp API v2 requests',
  labelNames: ['method', 'endpoint', 'status'] as const,
  registers: [registry],
});

const requestDuration = new Histogram({
  name: 'clickup_request_duration_seconds',
  help: 'ClickUp API request duration in seconds',
  labelNames: ['method', 'endpoint'] as const,
  buckets: [0.05, 0.1, 0.25, 0.5, 1, 2, 5],
  registers: [registry],
});

const rateLimitGauge = new Gauge({
  name: 'clickup_rate_limit_remaining',
  help: 'ClickUp rate limit remaining requests',
  registers: [registry],
});

const errorCounter = new Counter({
  name: 'clickup_errors_total',
  help: 'ClickUp API errors by status code',
  labelNames: ['status_code', 'error_type'] as const,
  registers: [registry],
});

Instrumented Client

async function instrumentedClickUpRequest<T>(
  path: string,
  options: RequestInit = {}
): Promise<T> {
  const method = options.method ?? 'GET';
  // Normalize endpoint for cardinality control (replace UUIDs)
  const endpoint = path.replace(/\/[a-zA-Z0-9]{6,}(?=\/|$|\?)/g, '/:id');
  const timer = requestDuration.startTimer({ method, endpoint });

  try {
    const response = await fetch(`https://api.clickup.com/api/v2${path}`, {
      ...options,
      headers: {
        'Authorization': process.env.CLICKUP_API_TOKEN!,
        'Content-Type': 'application/json',
        ...options.headers,
      },
    });

    // Update rate limit gauge
    const remaining = response.headers.get('X-RateLimit-Remaining');
    if (remaining) rateLimitGauge.set(parseInt(remaining));

    const status = response.ok ? 'success' : `${response.status}`;
    requestCounter.inc({ method, endpoint, status });

    if (!response.ok) {
      const body = await response.json().catch(() => ({}));
      errorCounter.inc({
        status_code: String(response.status),
        error_type: body.ECODE ?? 'unknown',
      });
      throw new Error(`ClickUp ${response.status}: ${body.err}`);
    }

    return response.json();
  } catch (error) {
    if (!(error instanceof Error && error.message.startsWith('ClickUp'))) {
      errorCounter.inc({ status_code: 'network', error_type: 'fetch_error' });
    }
    throw error;
  } finally {
    timer();
  }
}

OpenTelemetry Tracing

import { trace, SpanStatusCode } from '@opentelemetry/api';

const tracer = trace.getTracer('clickup-integration', '1.0.0');

async function tracedClickUpCall<T>(
  operationName: string,
  path: string,
  fn: () => Promise<T>
): Promise<T> {
  return tracer.startActiveSpan(`clickup.${operationName}`, async (span) => {
    span.setAttribute('clickup.path', path);
    span.setAttribute('clickup.method', 'GET');

    try {
      const result = await fn();
      span.setStatus({ code: SpanStatusCode.OK });
      return result;
    } catch (error: any) {
      span.setStatus({ code: SpanStatusCode.ERROR, message: error.message });
      span.recordException(error);
      throw error;
    } finally {
      span.end();
    }
  });
}

Structured Logging

import pino from 'pino';

const logger = pino({ name: 'clickup', level: process.env.LOG_LEVEL ?? 'info' });

function logClickUpCall(data: {
  method: string;
  path: string;
  status: number;
  durationMs: number;
  rateLimitRemaining?: number;
  error?: string;
}): void {
  const level = data.status >= 500 ? 'error' : data.status >= 400 ? 'warn' : 'info';
  logger[level]({
    service: 'clickup',
    ...data,
  }, `ClickUp ${data.method} ${data.path} -> ${data.status} (${data.durationMs}ms)`);
}

Alert Rules

# prometheus/clickup_alerts.yaml
groups:
  - name: clickup
    rules:
      - alert: ClickUpHighErrorRate
        expr: rate(clickup_errors_total[5m]) / rate(clickup_requests_total[5m]) > 0.05
        for: 5m
        labels: { severity: warning }
        annotations:
          summary: "ClickUp API error rate > 5%"

      - alert: ClickUpHighLatency
        expr: histogram_quantile(0.95, rate(clickup_request_duration_seconds_bucket[5m])) > 3
        for: 5m
        labels: { severity: warning }
        annotations:
          summary: "ClickUp P95 latency > 3s"

      - alert: ClickUpRateLimitLow
        expr: clickup_rate_limit_remaining < 10
        for: 1m
        labels: { severity: critical }
        annotations:
          summary: "ClickUp rate limit nearly exhausted"

      - alert: ClickUpAuthFailures
        expr: increase(clickup_errors_total{status_code="401"}[5m]) > 0
        labels: { severity: critical }
        annotations:
          summary: "ClickUp authentication failures detected"

Metrics Endpoint

app.get('/metrics', async (req, res) => {
  res.set('Content-Type', registry.contentType);
  res.send(await registry.metrics());
});

Error Handling

Issue	Cause	Solution
High cardinality	Dynamic IDs in labels	Normalize paths (replace IDs with `:id`)
Missing metrics	Uninstrumented code path	Wrap all API calls through instrumented client
Alert storm	Threshold too sensitive	Tune `for` duration and threshold
Trace gaps	Missing context propagation	Ensure span context is passed
