<p>I need this information to measure mean time to recovery (MTTR). I have tried using different kube-state-metrics but it does not seem to help much. Any hints on measuring MTTR will also be appreciated</p>

<p>You can use the pod status information, it records last transition time for each status signal. In this case you probably want the time difference between <code>PodScheduled</code> and <code>Ready</code>, but up to you to decide what counts as "startup time" or not (for example, does the time spent on pulling container images count?).</p>
