Connect Your First Site

GridNMS Cloud needs a collector inside your network to do the actual watching. The collector connects outbound to your GridNMS instance — you never open any inbound firewall ports. This page gets your first collector online.

New to collectors? Read What Is a Collector? first.

  • A Linux or macOS machine on the network you want to monitor (a small Linux VM is ideal — 1–2 CPUs and 1 GB RAM is plenty to start).
  • Administrator access on that machine (you’ll install with sudo).
  • Outbound HTTPS (443) access from that machine to your GridNMS instance.
  • Admin access to your GridNMS instance.
  1. In GridNMS, go to Configure → Collectors.
  2. Select Register collector and copy the one-time enrollment token it shows.

The Collectors page, where you add and manage collectors Configure → Collectors: register a collector and watch it come online.

Download the build for your machine from the Customer Portal → Downloads (sign-in required), then unpack it and run the installer with sudo:

Terminal window
tar xzf gridnms-collector-distro-<version>-linux-<arch>.tar.gz
cd gridnms-collector-distro-<version>-linux-<arch>
sudo ./linux/install.sh --join-token=<your-enrollment-token>

The installer prints a summary telling you whether it started and connected. Full download and install details, including firewall ports, are in Installing a Collector.

Back on Configure → Collectors, your new collector appears and turns online within a few seconds.

A collector only monitors the networks you assign to it:

  1. Go to Configure → Sites & Networks and pick (or create) the site.
  2. Add a network (an IP range in CIDR form) that the collector is responsible for.
  3. Open that network, select Assign Collector, and pick your collector. It begins watching devices in that range.
  4. Open the collector and turn on the services you plan to use — every service starts switched off. See Collector Services for what each one does.

More on this in Networks & Sites.

Your network is connected. Now add devices and see GridNMS in action:
