Overview
Servergraph Professional provides rigorous management of Tivoli Storage Manager (TSM) data protection environments to ensure 100% backup success. This product has powerful graphing and drill-down tools for quick problem isolation, performance tuning, and storage billing by application.
The following key features make Servergraph Professional an essential tool for all backup environments:
- Agentless technology allows you to view your total backup environment from a single Web-based console.
- Real-time alerting prevents missed backups.
- Predictions of future space run-outs maintain system reliability so you can plan your budget in advance.
- Data collection has a minimal impact on the storage servers that it monitors. To accomplish this, it gathers data through log file analysis, selective queries, and operating system tools.
- Activity log filtering capabilities focus on critical messages allowing you to quickly isolate and address errors in your environment.
- E-mail reporting tools can be automated to send daily reports to administrators at your site.
- User roles allows administrators to control who has access to different servers, nodes, and reporting tools within the Servergraph product.

Out of the box, Servergraph includes prebuilt alerts to notify you immediately of severe problems in your environment. The message-based alerts are customizable by error code and can be setup to send alerts via e-mail or SNMP traps. Other types of alerts that Servergraph uses to update you on the status of your backups include threshold, heartbeat, and prediction alerts.

The Servergraph Professional home page is a quick way to see what is happening in your TSM environment. At the top of this page, the 30-Day Backup Status Chart depicts the total number of completed backups, missed files, missed filespaces, missed nodes, unscheduled backups , unknown nodes, and ignored nodes. Each bar represents a day of backups, and you can click on any of these bars to drill down into a more detailed view of that day. The navigation tree on the left lists the many reports available at the enterprise level (all TSM servers) and at the individual storage server level (one TSM server).

The Backup Status History report is one of the new reports in Servergraph Professional. Several customers who wanted a 30-day view of backup success by node requested this report. The various backup categories are represented by color (completed, missed files, missed filespaces, missed entire node, unscheduled backups, unknown nodes, and ignored nodes).

Backup administrators find that the Unexpected Activity Log Messages is a great place to discover what errors are happening in their backup environment. Servergraph captures storage server activity log messages for the past 48 hours and stores them locally on the Servergraph server. When Servergraph is installed, it is configured to ignore almost 420 of the most common messages from the storage server activity log. These messages account for approximately 95 percent of the chatter in the activity log. What remains are the errors that you should be concerned about. After you address one of these error messages, add advice for you or your staff to follow the next time this error occurs. This feature is extremely valuable for operators and junior administrators.

The Administration GUI gives you direct access to the TSM server, thus serving as a replacement for the TSM Web GUI or the ISC. Only users assigned to the Administrators group (users with all privileges) can access this feature. The Administration GUI provides a single access point into all your TSM servers to view and change the content of various tables in the TSM database. A similar but more restricted console for changing content of TSM database tables is available for users who are not assigned to the Servergraph Administrators group.

The Health Check graphs show a single-page view of the health of a storage server, by displaying graphs for many aspects of storage server operation and performance (storage pools, tape drives, migration, expiration, reclamation, and database backup). You can drill down into each data type to display additional information specific to that data type. By default, this graph automatically discovers devices and pools that you add to your storage server. It also automatically discovers the daily jobs associated with data movement and storage server database maintenance.
Servergraph generates 3-Day and 8-Day graphs each day. The Now graph is a Health Check graph for the past 24 hours. This graph is generated immediately with up-to-the-minute information when you select it from the Navigation Tree.

The Node Sessions graph provides a visual display of backup activity and shows what slows down backups. Each client session is represented with a horizontal bar graph. These sessions are most often backups, but can also be restores, archives, or retrieves. The left edge of the bar shows the session start time, and the length shows how long the session lasted. The height of the bar indicates session speed. The bar graphs use different color lines to represent idle wait, media wait, communication wait, and successful transmission. The color bars are explained in the legend at the bottom of the page.

The SQL Report Writer (Trapped Data Report) is a quick and easy way to generate virtually any report you want. The report writer has several tables where you simply choose columns (operations are allowed on the fields), orderings, and groupings; build constraints; and then save the report. The new report appears on the navigation tree.

The Storage Abusers report shows client nodes that use more storage on the backup server than they own locally. In this report, the Hog Factor data type measures this overuse. It is calculated as on-site storage (on the storage server) divided by capacity used locally (on the node itself). This report is a direct reflection of your TSM server’s retention. If you keep manual copies of each backup, you will see a higher hog factor.

The Filespaces Missed report provides drill-down capability depicting those filespaces that are not being backed up. You can clearly see how many days it has been since a good backup has taken place. Filespaces can be missed for many reasons; often it is because an administrator either renamed or deleted the filespace on the node without informing the backup administrator.
