NetScaler MAS polls managed instances to collect information. The following list describes the various kinds of polling that occur between NetScaler MAS and managed instances, the protocols used to collect this information, and whether the polling intervals can be configured on the NetScaler MAS server.
NetScaler MAS also allows you to poll configuration audits manually and adds all the configuration audits of the instances immediately to the NetScaler MAS. To do so, navigate to Networks > Configuration Audit, click Poll Now, the pop-up page Poll Now provides you an option to poll all NetScaler instances in the network, or poll the selected instances.
NetScaler MAS allows you to poll SSL Certificates and add all the SSL certificates of the instances immediately to NetScaler MAS. To do so, navigate to Networks > SSL Dashboard and click Poll Now. The Poll Now page pops up, presenting the option to poll all NetScaler instances in the network or poll selected instances.
In addition to polling, events generated by managed NetScaler instances are received by NetScaler MAS through SNMP traps sent the instances. For example, an event is generated when there is a system failure or change in configuration.
During instance backup, SSL files, CA certificate files, NetScaler templates, database information, and so on are downloaded to NetScaler MAS. During a configuration audit, ns.conf files are downloaded and stored in the file system. All information collected from managed NetScaler instances are stored internally within the database.
