Configure System Settings for Optimal NetScaler MAS Performance

Before you start using NetScaler MAS to manage and monitor your instances and applications, configure a few system settings to ensure optimal performance of your NetScaler MAS server.

System Settings Description How to Configure
Configure System Alarms Configure system alarms to make sure you are aware of any critical or major system issues. For example, you might want to be notified if the CPU usage is high or if there are multiple login failures to the server. For some alarm categories, such as cpuUsageHigh or memoryUsageHigh, you can set thresholds and define the severity (such as Critical or Major) for each. For some categories, such as inventoryFailed or loginFailure, you can define only the severity. When the threshold is breached for an alarm category (for example, memoryUsageHigh) or when an event occurs corresponding to the alarm category (for example, loginFailure), a message is recorded in the system and you can view the message as syslog message. 1. Navigate to System > Alarms, select the alarm you want to configure, and click Edit. 2. On the Configure Alarm page, select the alarm severity, and set the Threshold. 3. To view the alarms that have breached the threshold or for which an event has occurred, navigate to System > Auditing and click Syslog Messages.
Configure System Notifications You can send notifications to select groups of users for various system-related functions. Set up a notification server in NetScaler MAS, and you can configure email and Short Message Service (SMS) gateway servers to send email and text notifications to users. You are notified of any system-level activities such as user login or system restart. 1. Navigate to System > Notifications. Under Settings, click Change Notification Settings. 2. On the Configure System Notification Settings page, select the category or category of events generated by NetScaler MAS. 3. Then, configure either the email server or the SMS server to receive notification through email or SMS or both.
Configure System Prune Settings To limit the amount of reporting data being stored in your NetScaler MAS server’s database, you can specify the interval for which you want NetScaler MAS to retain network reporting data, events, audit logs, and task logs. By default, this data is pruned every 24 hours (at 00.00 hours). 1. Navigate to System > System Administration. Under Prune Settings, click System Prune Settings. 2. In the Configure System Prune Settings page, specify the number of days for which to retain data, and click OK.
Configure System Backup Settings NetScaler MAS automatically backs up the system everyday at 00:30 hours. By default, it saves three backup files. You might want to retain more number of backups of the system. You can also encrypt the backup file. You can also choose to save the backup on an external server. 1. Navigate to SystemSystem Administration. 2. Under Backup Settings, click System Backup Settings. 3. On the Configure System Backup Settings page, specify the required values.
Configure Instance Backup Settings If you back up the current state of a NetScaler instance, you can use the backup files to restore stability if the instance becomes unstable. Doing so is especially important before performing an upgrade. By default, a backup is taken every 12 hours and three backup files are retained in the system. 1. Navigate to System > System Administration. 2. Under Backup Settings, select Instance Backup Settings, and specify the required values.
Configure Instance Event Prune Settings To limit the amount of event messages data being stored in your NetScaler MAS server’s database, you can specify the interval for which you want NetScaler MAS to retain network reporting data, events, audit logs, and task logs. By default, data is pruned every 24 hours (at 00:00 hours). 1. Navigate to System > System Administration. 2. Under Prune Settings, click Instance Events Prune Settings. 3. Enter the time interval, in days, for which you want to retain data on the NetScaler MAS server and click OK.
Configure Instance Syslog Purge Settings To limit the amount of syslog data stored in the database, you can specify the interval at which you want to purge syslog data. You can specify the number of days after which the following syslog data is deleted from NetScaler MAS: Generic Syslog Data, AppFirewall Data, and NetScaler Gateway Data. 1. Navigate to System > System Administration. Under Prune Settings, click Syslog Purge Settings. 2. In Configure Syslog Purge Settings page, enter the required values. 3. Select the Configure NetScaler Gateway Purge Interval by Syslog Type checkbox to take precedence over the purge settings interval configured to retain the NetScaler Gateway data. 4. Select one or more of the following options and click OK. Type - The type of NetScaler Gateway syslog types generated on the devices, such as Login, Logout, Login failed, ICA proxy session start, and others. Select the type for which you want syslog data deleted from the NetScaler MAS server. Purge Interval (Days) - The time interval between two successive purge operations performed on syslog data.
