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
