Feature Server Production SLOs
This page details the Service Level Objective (SLO) for the Feature Server that Tecton commits to upholding. The SLO covers Reliability, based on Service Level Indicators (SLIs) described below. The indicators are determined by Tecton on the server side, and compliance with the SLO is evaluated on a 30 day rolling period.
Reliability​
The SLI for reliability is the percentage of requests which do not return a server error (HTTP 5xx). For the purpose of this indicator, client errors (HTTP 4xx) are not considered errors. Additionally, requests which time out on the server side and return 504 do not count against the reliability SLI.
The objective for this indicator is 99.95%.
SLO Indicators in the Web UI​
Monitoring for the reliability SLO is available in the Web UI under the monitoring tab for each Feature Service and the overall Monitoring page. In addition to the rate of SLO violations, the rate of requests to the service which are not SLO-Eligible is shown.
SLO Violations​
If an SLO violation is detected by Tecton, a Tecton on-call engineer will be immediately alerted to respond to the situation within 1 hour, 24/7.
If a customer detects what appears to be an SLO violation which is not reflected in the SLO indicator in the Web UI, a Tecton engineer will respond to service requests within 8 hours, during business hours.
