FAQ Report Generator (GGUS)


Contents


The GGUS Report Generator is available at https://ggus.eu/?mode=report_view.

Definitions and prerequisites

The implementation of the report generator started in October 2011. Hence the report generator does not provide data for tickets submitted before December 2011!

Timestamps and metrics

Response time

The response time is a performance figure calculated from the support unit's point of view. It describes how quick a support unit is reacting on tickets. Response time is the time from

The response time is calculated as difference between the time stamp changing the status or re-assigning the ticket and the assign time stamp. While assigning a ticket to a support unit the expected response time stamp is calculated by adding an amount of time to the assign time stamp. The amount of time added depends on the ticket priority and the kind of support unit. For support units that have declared a quality of service level the response times are defined by the QoS level. For all the other support units a medium QoS is assumed for calculating the expected response time stamp. In case the actual response time stamp is greater than the "expected response" time stamp for middleware support units the "violate" flag is set.
Response times are based on office hours. Hence the results unit is working days.

Solution time

The solution time is a performance figure also calculated from the support unit's point of view. It describes how long it took the support unit for providing a solution. Solution time is the time from assigning a ticket to a support unit until it provides a solution for the problem described. "Providing a solution" means setting the ticket status to "solved" or "unsolved". The solution time is calculated as the difference between the solution time stamp and the assign time stamp.
Solution times are based on office hours. Hence the results unit is working days

Waiting time

Waiting time is the sum of all time slots the ticket was set to "waiting for reply". Calculating the waiting time has started in July 2012. For tickets submitted before July 2012 no waiting time calculation was done. The waiting time for these tickets may be zero. The waiting time can be excluded when calculation solution times by ticking the check box "exclude waiting time".

Ticket lifetime

The ticket lifetime is calculated from the user's point of view. It describes how long it takes to provide a meaningful solution for a problem reported by the user. Ticket lifetime is the time from ticket submission to ticket solution (status "solved/unsolved").
The ticket lifetime is based on calendar days.

Time zones

GGUS support units are spread over a wide range of time zones. Some of the support units themselves are spread over several time zones. However most support units are located in European time zones.
Support units and their time zones are listed at https://ggus.eu/?mode=resp_unit_info.

For middleware product teams GGUS assumes time zone "UTC +1" for all support units.
For all the other support units the system uses the relevant time zone for calculating timestamps as far as possible.

Office hours

The systems assumes usual office hours from 09:00 to 17:00 Monday to Friday for all support units. National holidays are not taken into account. For middleware product teams the timezone UTC+1 is used as default timezone.

Ticket priorities

For the calculation of performance figures the original priority set during ticket submission is used. This priority value is kept as long as the support unit is in charge of the ticket. Updating the priority value during ticket lifetime doesn't affect the calculation of performance figures.

Unit abbreviations

Reports description

Although some of the drop-down lists request the selection of values a query can be started anyway. In this case the query is equivalent to a query over all tickets!
The "Reset" button resets all fields to their default settings besides the time frame.

Tickets submitted

This metric gives the number of tickets submitted within the specified time frame.
Major criteria is the submit time stamp.
The result lists shows the current status of the tickets.

Open tickets time

The open tickets time report calculates the time from ticket submission until now in calendar days. The submit time stamp must match the specified time frame for the report.

Tickets closed

This metric is focused on the ticket life time. It gives the number of tickets that reached the status "solved" or "unsolved" within the specified time frame. Major criteria is the solution time stamp which is the time stamp setting a ticket to "solved" or "unsolved". Tickets in other terminal status like "verified" or "closed" appear in the result list as long as they have been set to "solved/unsolved" in the given time frame. Besides date, status and the number of closed tickets the results list displays the average ticket lifetime and the median ticket lifetime. The result lists shows the current status of the tickets.

Response time

This metric focuses on the responsiveness of support units.
Major criteria for this report is the submit time stamp which must match the selected time frame. The result list shows

for the specified time frame. The result list shows all support units that have ever been in charge of a ticket. Hence the same ticket ID may appear several times. The number of responses may be greater than the number of tickets.
Response times are based on office hours. Hence an average response time of 1d 3h 23min means 13 hours and 23 minutes in total.

Violated response time

Specific privileges are required for this report. Only people belonging to a dedicated technology provider (TP) are able doing reports for this TP. Major criteria for this report are the expected response time defined in SLAs and the TP.

Solution time

Major criteria for this report is the solution time stamp. The result list shows

for the specified time frame. The result lists shows the current status of the tickets.
Solution times are based on office hours. Hence an average solution time of 12d 3h 5min means 99 hours and 5 minutes in total.
The waiting time can be excluded by ticking the check box "exclude waiting time".
In case a ticket gets re-opened the metrics calculation starts again from scratch. Hence the same ticket can appear several times in the solution times calculation.


Input parameters and results

Input parameters

The input parameters vary depending on the report type chosen. Possible input parameters are

Time frame
The time frame defines begin and end date of the report. The begin date starts at 00:00:00. The end date ends at 00:00:00.
As the implementation of the report generator started in October 2011 the report generator does not provide data for tickets submitted before December 2011!

Responsible Units
The drop-down list offers all responsible units integrated in GGUS system. They can be filtered by keywords. Responsible Units can be either selected all, one by one or by checking the boxes in front of the responsible unit groups. In case no responsible units are selected all responsible units are considered in the reports.

Status
The drop-down list offers all status values available in GGUS system. Multiple selections are possible.

Priority
The drop-down list offers all priority values available in GGUS system. Multiple selections are possible.

Concerned VO
"Concerned VO" provides a drop-down list of all VOs supported by GGUS. Multiple selections are possible.

Ticket type
This drop-down list lists all ticket types in GGUS. Multiple selections are possible.

Ticket category
Selectable categories are "Incident", "Change request", "Documentation", "Test". Multiple selections are possible. The category "Test" should not be considered for all reports and therefore, if necessary, be excluded from the selection.

Notified site
"Notified site" lists all sites integrated in GGUS. They are derived from GOC DB and OIM DB.
In case of reporting exclusively on tickets without any site value specified please ticket the "<blank>" value in the drop-down list.

Technology Provider
This input parameter is only visible if choosing the "violated response time" report. For accessing this report specific privileges are required. The drop-down list offers all technology providers currently integrated in GGUS and the "DMSU". Multiple selections are possible. In case no technology provider is selected the reports will be done for tickets without any technology provider specified.

Date aggregation
The results aggregation level can be chosen from the drop down list "Choose date aggregation".

Group by
Results can be grouped by one or more of the input parameters.

Results

The results are displayed below the input parameter area. They can be sorted in different ways by clicking on the column labels. A drill-down is possible by clicking on any row of the results list. The detail results open in a new window. They can be sorted by clicking the column labels too. Clicking on the ticket ID opens the ticket in GGUS system. At the bottom of the result panel there are various icons offering features like

Doing a simple "Export" saves the data in a csv file stripping all column headers. For exporting the data including the column headers please use "Export what you see".
The "Search" feature allows searching in the result list. Possible search parameters are the columns of the result list.
