How to Monitor InfluxDB with Vigilmon

InfluxDB is the leading time-series database for metrics, events, and real-time analytics. It's commonly used for IoT telemetry, application performance monitoring, and financial data. But InfluxDB itself needs monitoring — if your metrics database goes down, you're blind to everything else.

This guide shows how to monitor InfluxDB availability and health using Vigilmon.

What to Monitor in InfluxDB

  • HTTP API availability — InfluxDB exposes a health endpoint
  • Query responsiveness — Can the DB accept and return data?
  • Write performance — Are writes being accepted without errors?
  • Disk space — Is the storage filling up?
  • Retention policy jobs — Are compaction and retention tasks running?

Step 1: Use the Built-In Health Endpoint

InfluxDB 2.x and InfluxDB Cloud expose a /health endpoint:

curl https://your-influxdb-host:8086/health
Enter fullscreen mode Exit fullscreen mode

Expected response when healthy:

{
  "checks": [],
  "commit": "abc123",
  "message": "ready for queries and writes",
  "name": "influxdb",
  "status": "pass",
  "version": "2.7.0"
}
Enter fullscreen mode Exit fullscreen mode

For InfluxDB 1.x:

curl http://your-influxdb-host:8086/ping
# Returns HTTP 204 when healthy
Enter fullscreen mode Exit fullscreen mode

Step 2: Add the Health Endpoint to Vigilmon

  1. Sign up at vigilmon.online
  2. Click Add Monitor → HTTP/HTTPS Monitor
  3. URL: https://your-influxdb-host:8086/health
  4. Expected HTTP status: 200
  5. Expected keyword in response: "status":"pass" (for InfluxDB 2.x)
  6. Check interval: 1 minute
  7. Alert via email or Slack on failure

For InfluxDB 1.x using /ping:

  • URL: http://your-influxdb-host:8086/ping
  • Expected status: 204

Step 3: Monitor the Write API

For a deeper check, add a monitor that verifies writes work:

#!/bin/bash
# check-influxdb-write.sh — run as a cron job

RESPONSE=$(curl -s -o /dev/null -w "%{http_code}" \
  -X POST "http://your-influxdb-host:8086/api/v2/write?org=myorg&bucket=health-checks" \
  -H "Authorization: Token ${INFLUXDB_TOKEN}" \
  -H "Content-Type: text/plain; charset=utf-8" \
  --data-binary "health_check value=1 $(date +%s%N)")

if [ "$RESPONSE" = "204" ]; then
  curl -s "https://hb.vigilmon.online/your-heartbeat-id" > /dev/null
fi
Enter fullscreen mode Exit fullscreen mode

Step 4: Set Up a Heartbeat Monitor

Create a Vigilmon heartbeat monitor and ping it from:

  • Your InfluxDB write-check script (cron)
  • Your application code after each successful batch write
  • Your Telegraf agent after each successful flush 
# telegraf.conf — send heartbeat after each successful flush
[[outputs.http]]
  url = "https://hb.vigilmon.online/your-heartbeat-id"
  method = "GET"
  # [outputs.http.headers] optional auth headers
Enter fullscreen mode Exit fullscreen mode

Alerting Strategy

Alert Condition Severity Response
/health returns non-200 Critical Page on-call immediately
/health response > 5s Warning Investigate disk/memory
Write API returns error Critical Check retention/disk space
Heartbeat missed High Check Telegraf/app config

InfluxDB Cloud Monitoring

If you're on InfluxDB Cloud, monitor your organization's health endpoint:

https://us-east-1-1.aws.cloud2.influxdata.com/health
Enter fullscreen mode Exit fullscreen mode

Even managed services have outages — Vigilmon gives you independent verification.

Conclusion

Don't let your metrics store go dark silently. Vigilmon gives InfluxDB a simple external health check that alerts you before data loss or gaps in your dashboards.
