Linode monitoring: all your Linodes in one dashboard

Linode emails alerts on CPU, disk I/O and traffic but not memory or disk space. Opyntel’s Linode monitoring adds both and shows every Linode at a glance, plus the other systems you run.

Built in vs Opyntel

Linode on its own, and Linode with Opyntel

Feature by feature, the biggest gaps first: what Linode gives you, and what you get in one dashboard with Opyntel.

Every Linode at a glance

On Linode

In Cloud Manager each Linode has its own summary of CPU usage, IPv4 and IPv6 traffic and disk I/O, and its own Alerts tab.

With Opyntel

Opyntel shows the full list of your Linodes in one table with state, memory, disk and load, down and degraded first, so you see it all at a glance. Akamai sits next to the other systems you run, in one dashboard.

Alerts on memory and disk space

On Linode

Email alerts cover CPU usage, disk I/O rate, incoming and outbound traffic and transfer quota, with CPU at 90% by default. Memory and disk space are not among the alert types.

With Opyntel

Opyntel alerts when a server goes down, memory passes your threshold, a disk passes 85% or 95%, or a disk is on track to fill. Each alert notifies when it fires and again when it recovers, by email, Slack or SMS depending on your plan.

Memory from inside the server

On Linode

Longview is an agent you install that tracks CPU, memory and network bandwidth in aggregate and per process. The free plan updates every 5 minutes for up to ten clients; Longview Pro updates every 60 seconds at an added cost.

With Opyntel

The Opyntel agent reports memory, disk fill level, load and per-container CPU, memory and restarts with one docker run command, using outbound HTTPS only. The numbers land in the same dashboard as your other platforms.

History

On Linode

Longview’s free plan keeps 12 hours of history; Longview Pro keeps the complete history.

With Opyntel

Opyntel keeps the same memory, disk and load history for 30 days on the free plan, a year on Pro and unlimited on Enterprise, with no separate add-on.

The total cost of your app

On Linode

Linodes are billed by the hour, and most plans stop at a monthly rate. Accrued charges show on the Billing page in Cloud Manager, and powered-off Linodes still incur charges.

With Opyntel

Opyntel shows a list-price cost estimate per Linode on Pro and adds it to the other platforms you run, so you see the total cost of your app at a glance. Monthly budget alerts and forecasts come with Enterprise.

Setup

How to set up Linode monitoring with Opyntel

Linode monitoring in four steps: from Linode to one dashboard with everything else you run.

  1. Create a read-only Linode personal access token
    In Cloud Manager, open your profile, then API Tokens, and create a personal access token with Read Only access to Linodes and No Access to everything else.
    Create a Linode API token
  2. Sign in to Opyntel
    Open your Opyntel dashboard and add a source. Accounts start from the waitlist, so join it to get yours.
  3. Paste the token and start the agent
    Paste the token. For memory, disk fill level and per-container CPU and memory, run the docker run command your dashboard shows on each of your Linodes: the agent sends over outbound HTTPS only and opens no port.
  4. See Linode in one dashboard
    Linode monitoring lands next to the other platforms you run: every service and server sits in one dashboard, down and degraded first, with default alert rules on from the start.

Don’t see your platform? From your Opyntel account you can request an integration with more platforms. Until then, and tell us which one you run on.

FAQ

Linode questions, answered

Short answers; some link to a guide that goes into detail.

Linode email alerts cover CPU, disk I/O and traffic, not disk space. Opyntel’s agent alerts on it. Find what filled a Linux disk.

Cloud Manager graphs CPU, disk I/O and traffic; memory needs Linode’s Longview agent, or free -h on the server. Opyntel’s agent alerts when memory passes your threshold. Check memory usage on Linux.

Find the process with top, and compare the load average with the core count; high steal time means a busy host. Opyntel shows load and CPU per Linode. Read the Linux load average.

Check status.linode.com first. If every Linode in a region fails together it is the platform; if one fails alone it is that server. Opyntel checks your public endpoints from several regions and alerts when one goes down.

Linodes add outbound transfer to an allowance pooled across your account (per region in some data centers), and overage is billed. Opyntel’s agent shows outbound traffic per server, so you see which one uses it.

The alerts your platform doesn’t send.

One dashboard for everything you run, with the alerts your platforms leave out. Read-only, nothing to install in your apps.
