The Auvik collector serves as the eyes and ears of your network infrastructure remote monitoring and management system. The collector depends on Layer 3 connectivity to different subnets to discover and monitor your clients’ devices. In certain cases, it makes sense to deploy multiple collectors to monitor different segments of your network. There’s no additional charge to deploy more than one collector.
You might want to deploy additional collectors in these situations:
- You have multiple physical sites that aren’t Layer 3 reachable to or from each other.
- You have some network segments that are completely segregated from each other (either physically or logically) and you want to keep them that way.
- You want a backup collector in case the primary collector’s host encounters issues.
We recommend you supply a description for every collector set up on a client network. This will help you better identify which collector is managing which subnet.
What happens when one collector goes offline
You can run multiple collectors on a single network for failover purposes, as long as each collector can talk to all subnets on the network. If one collector goes offline, the other will immediately take over scanning.
If you have collectors running on different subnets that aren’t able to communicate, each collector continues to manage its subnet only. In other words, if a collector for subnet A goes offline, the collector for subnet B will not take over scanning.
How to add an additional collector
When a client is first set up, you must start an Auvik collector to begin the discovery process. For an additional collector to talk to subnets the first collector doesn’t have access to, the additional collector must be installed on a host that has access to the other subnets you’d like managed.
- Place a copy of the additional collector on the second host. This can be done in one of two ways:
- Deploy your additional collector on the host machine. Let the collector initialize.
- From the client’s Auvik dashboard, click Auvik Collectors in the side navigation bar. You should now see an additional collector entry, which appears as Connected and Pending. Approve the new collector.
How to set an additional collector to scan subnets
The initial collector will have discovered all the subnets to which it has access. But there may be other subnets you’d like managed that the initial collector can’t to talk to. An additional collector can be set to scan these other subnets.
First, add the new subnet to your client’s dashboard. Once Auvik starts scanning the subnet, you’ll be able to see which collector is managing it from the list of Routed Networks.
