We released Linux Agent 4.0.11 today. This update brings Kerio Connect Server monitoring to the new Linux agent, and fixes a quiet but important problem with how expirations reported by Linux plugins were being saved.
Here’s what it does for Kerio Connect Server:
- Detects Kerio on its own by looking for the license file at `/opt/kerio/mailserver/`. On a host that isn’t running Kerio it reports informationally and stays out of your way, so there’s nothing to enable, deploy, or scope to a group.
- The plugin reads Kerio’s license file directly and reports the Base ID, license expiration, subscription expiration, licensed user count, and the registered company and contact email.
- Both dates are also reported as proper expirations — Connect (License) and Connect (Product) — so they land in your dashboard’s expirations list and give you the same advance renewal warning you already get for other tracked products.
- Kerio can be configured to run a service that isn’t actually up. The plugin reads every service set to start automatically, along with the IP addresses and ports each one is configured to bind, then checks those against the ports genuinely in a listening state on the machine. If a configured service isn’t answering, you get a specific warning naming the service and the address it should be on — for example, `WARNING: SMTPS is not responding on 0.0.0.0:465.` The full list of active services and their bindings is included in the report either way, so you can see the server’s configured surface at a glance.
- For each configured domain, the report shows the enabled user count (disabled accounts are excluded, so the number reflects real seats in use), the domain’s maximum user count where one is set, its total mail storage, and the size of its public folders.
- Kerio spreads its data across several configurable locations, and the ones that grow are not always the ones you’re watching. The plugin reports the configured path and current size for the Mailstore, Backups, Archives, Logs, Full Text Search index, and Instant Messaging store.
