# Investigating Azure Pipelines builds
This document contains useful patterns for inspecting Azure Pipelines builds.
## How to view the build timeline
Use `Show-BuildTimeline.ps1` to view a build's timeline.
This includes all stages, jobs, and tasks along with their results.
```shell
pwsh ./eng/docker-tools/skill-helpers/Show-BuildTimeline.ps1 <org> <project> <buildId>
```
Each node includes a log ID (`Task #42` means log ID 42).
## How to read pipeline logs
First, get the log ID from the build timeline.
Then, use `Get-BuildLog.ps1` to print the full log:
```shell
pwsh ./eng/docker-tools/skill-helpers/Get-BuildLog.ps1 -Organization dnceng -Project internal -BuildId $buildId -LogId $logId
```
