How is the Performance Calculated?
"Transaction Time" means the time a transaction takes place (in milliseconds) from when it is received by the system, until the system processes and returns a response, measured on the server.
The average performance calculation is based on the following calculation
The 95% measure is calculated by aggregating all relevant transactions, ordering them from smallest to largest, and then identifying the time that 95% out of all transactions are faster (less) than this time.
Note that the performance measures are measured across all institutions within the instance.
Examples:
- An API call to Higher-Ed Cloud Platform: from the time a request was received in the system until the full API response (in whatever format chosen) was processed and sent back to the calling application
- The ‘All Titles’ screen in Alma: from the time the search query was received in the system until the full result was processed and the page of actual results was generated and sent back to the browser for rendering.
- The resource list display in Leganto: from the time that the system receives a request for a resource list until the list is generated and sent back to the browser for rendering.
- Please Note: Analytics API is excluded from the above calculation.

How is Uptime Calculated?
The uptime calculation is based on the following calculation (as defined in the Service Level Agreement):
"Uptime" means the total period in minutes during which the Service is available for access and use during this period.
“Uptime Percentage” means Uptime expressed as a percentage, calculated by the following formula:
Uptime Percentage = X /(Y–Z) × 100
Where:
X = Uptime
Y = Last 12 months period
Z = The duration (in minutes) of any SLA Exclusions* during these 12 months
*SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
