Manage Edge Server
The Edge server is a Gateway to the Internet provided by Microsoft, and is essentially used as an anti-spam server. It filters the mail coming from the outside and gives it to the HUB server, then takes the messages from the HUB to deliver to the Internet. GSX makes the difference between critical and non-critical services. Depending on the role selected for a server, GSX proposes to pre-populate a list of critical services adding them automatically to this list.
GSX Monitor & Analyzer main features
Monitoring of the Edge server critical Windows services
GSX provides a list of all critical window services that must run on the Edge Role server, and checks and alerts if one is down. Admins can also add optional non-critical window services to the monitor.
General availability through PowerShell system checks
GSX connects on the server through PowerShell. It also collects System statistics through WMI. The general availability is determined by identifying how possible it is to connect on the server and the status of the critical Windows Services. In addition to this status, what matters most is monitoring all services provided by the Edge role.
Availability of the Edge transport
External Mail Routing test: GSX sends a piece of mail from any mailbox to an Internet Echo service (automatically sent back an email received). The piece of mail is sent back by the Echo service and transported to the correct mailbox on the way back. This check tests the ability of the HUB to transport mail from the DB, through the EDGE / Gateway to the Internet both ways, and lets administrators know how long it takes for a user to send and receive mail from the Internet. The result of this test is one of the fundamental statistics to follow as it tests the main usage of the Exchange architecture.
Alerts are sent if the test fails and details of the errors are available in the Scenario View.
Disk space alert
GSX allows administrators to set up alerts on disks attached to any Exchange server. The alert is sent if the available space is below a certain amount of megabytes (MB) or percentage of the disk. It allows administrators to be proactive and not to wait until a storage problem arrives which will then need to be fixed.
We know that servers must have some maintenance windows, and GSX gives customers the opportunity to set up monitoring maintenance windows using the Time zone feature. During this maintenance time GSX will not send alerts, and will separate the statistics in order to not interfere with the Service Level Agreements (SLAs). Two set of statistics will be reported in Analyzer: Normal statistics and maintenance statistics.
Reporting on the EDGE role
- General availability
Availability and Performance: Server Up, Down, average access time, longest downtime, network, CPU, RAM, disk space are very useful, to calculate the availability of the server and detect System problems (CPU overload, not enough, RAM, problem of availability, etc..).
- Mail Routing Statistics:
GSX continuously calculates average and maximum delivery times of a complete circle from the SMTP server through the EDGE to the Internet and back. This test also measures the availability of the EFGE service linked to the HUB.
Administrators can set 2 different timeouts (SLAs).
GSX Analyzer reports on the percentage of success of the first SLA, the average delivery time, max delivery time, minimum routing time and percentage of success of the second SLA.
GSX Analyzer gives administrators the ability to trend this statistic in order to detect any Edge server performance problems.
These statistics reflect the availability and performance of the entire service delivered by the HUB and EDGE / Gateway servers of the organization when the probe is sent to the Internet.
