Zimbra
Overview
The Zimbra integration with Motadata ObserveOps enables performance, availability, and capacity monitoring of the Zimbra Collaboration Suite. It collects metrics across LDAP, mailboxes, IMAP/POP3, SOAP sessions, garbage collection, memory pools, mail queues, and indexing components.
This documentation lists all supported KPIs categorized by subsystem, with descriptions for each metric.
Prerequisites
Ensure the following prerequisites are met:
- Zimbra server must be reachable over the network.
- SNMP or API access must be configured and allowed.
- Credentials with appropriate permissions must be available.
- Device must be added through the ObserveOps discovery module using supported protocol.
