Grafana metrics: Might want to introduce additional rate metrics that subtract the header overhead to have the pure payload: low priority.

Backpressure reporting when there is only 1 input channel https://its.cern.ch/jira/browse/O2-4237
- using testworkflows
  - simple-source
  - simplified dummy-workflow
    - one input, one output channel
    - taking simple-source output as input
  - putting one processor to sleep for 1s to create backpressure
    - backpressure correctly reported by processers in front

Merged workflow fails if outputs defined after being used as input
- needs to be implemented by Giulio
Cannot override options for individual processors in a workflow
- requires development by Giulio first
Problem with 2 devices of the same name
Usage of valgrind in external terminal: The testcase is currently causing a segfault, which is an unrelated problem and must be fixed first. Reproduced and investigated by Giulio.
Run getting stuck when too many TFs are in flight.
Do not use string comparisons to derrive processor type, since DeviceSpec.name is user-defined.
Support in DPL GUI to send individual START and STOP commands.
DPL sending SHM metrics for all devices, not only input proxy
- moved checking for readout-proxy name from when sending the metric to when registering the metric
  - sending the metric only when registered
  - tested locally with GUI
- calibrations on aggregator nodes have different proxy names
- standalone calibration sometimes have different input proxy names
- tested locally with raw-proxy
- merged
Add additional check on DPL level, to make sure firstOrbit received from all detectors is identical, when creating the TimeFrame first orbit.
Implement a proper solution to detect wheter a device is firstInChain
Deploy topology with DPL driver

Check if we can remove dependencies on /home/epn/odc/files in DPL workflows to remove the dependency on the NFS
- reading / writing already disabled
- remaining checks for file existence?
- check after Pb-Pb by removing files and find remaining dependencies
logWatcher.sh and logFetcher scripts modified by EPN to remove dependencies on epnlog user
- node access privileges fully determined by e-groups
- new log_access role to allow access in logWatcher mode to retrieve log files, e.g. for on-call shifters
- to be validated on STG
- waiting for EPN for further feedback and modifications of the test setup
