3 SLA
Overview
Once the services are created, you can start monitoring whether their performance is on track with service level agreement (SLA).
Services->SLA menu section allows to configure SLAs for various services. An SLA in Áú»¢¶Ä²© defines service level objective (SLO), expected uptime schedule and planned downtimes.
SLAs and services are matched by service tags. The same SLA may be applied to multiple services - performance will be measured for each matching service separately. A single service may have multiple SLAs assigned - data for each of the SLAs will be displayed separately.
In the SLA report Áú»¢¶Ä²© provides Service level indicator (SLI) data, which measures real service availability. Whether a service meets the SLA targets is determined by comparing SLO (expected availability in %) with SLI (real-life availability in %).
Configuration
To create a new SLA, click on the Create SLA button.
The SLA tab allows to specify general SLA parameters.
| Parameter | Description |
|---|---|
| Name | Enter the SLA name. |
| SLO | Enter the service level objective (SLO) as percentage. |
| Reporting period | Selecting the period will affect what periods are used in the SLA report - daily, weekly, monthly, quarterly, or annually. |
| Time zone | Select the SLA time zone. |
| Schedule | Select the SLA schedule - 24x7 or custom. |
| Effective date | Select the date of starting SLA calculation. |
| Service tags | Add service tags to identify the services towards which this SLA should be applied. Name - service tag name, must be exact match, case-sensitive. Operation - select Equals if the tag value must match exactly (case-sensitive) or Contains if part of the tag value must match (case-insensitive). Value - service tag value to search for according to selected operation. The SLA is applied to a service, if at least one service tag matches. |
| Description | Add a description for the SLA. |
| Enabled | Mark the checkbox to enable the SLA calculation. |
The Excluded downtimes tab allows to specify downtimes that are excluded from the SLA calculation.
Click on Add to configure excluded downtimes.
SLA reports
How a service performs compared to an SLA is visible in the SLA report. SLA reports can be viewed:
- from the SLA section by clicking on the SLA report hyperlink;
- from the Services section by clicking on the SLA name in the info tab;
- in the Dashboard widget SLA report.
Once an SLA is configured, the Info tab in the services section will also display some information about service performance.
