Please check this page if you face any problem with setting up GrimoireLab. If you didn’t find the solution for your proble, please open an issue in the chaoss/grimoirelab repository. If you found out the reason, and would like to add it to this section, please feel free to open a pull request to the chaoss/grimoirelab-tutorial repository.

If something goes wrong during the docker-compose setup, run the docker-compose command without the -d or --detach flag. That will allow you to see all the logs while starting/(re)creating/building/attaching containers for a service.

  cd grimoirelab/docker-compose
  docker-compose up

Port already in use

It may also happen that the port, 5601, is already allocated to some other container. So running docker-compose will lead to the following error

WARNING: Host is already in use by another container

In order to fix it, you need to see which container is using that port and kill that container.

docker container ls   # View all running containers

Empty dashboard or visualization

Usually this is a matter of time for GrimoireLab to fetch the data from the configured data source. However It may happen that some filters might be activated. You can see whether a filter is active by looking at the filter bar as shown in the following screenshot or the time window.


Low Virtual Memory


Cannot open https://localhost:9200/ in browser. Shows Secure connection Failed, PR_END_OF_FILE_ERROR, SSL_ERROR_SYSCALL in connection to localhost:9200 messages.


Check for the following log in the output of docker-compose up

elasticsearch_1  | ERROR: [1] bootstrap checks failed
elasticsearch_1  | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]


Increase the kernel max_map_count parameter of vm using the following command.

sudo sysctl -w vm.max_map_count=262144

Now stop the container services and re-run docker-compose up. Note that this is valid only for current session. To set this value permanently, update the vm.max_map_count setting in /etc/sysctl.conf file. To verify after rebooting, run the below command.

sysctl vm.max_map_count

Processes have conflicts with SearchGuard


Cannot open localhost:9200 in browser, shows Secure connection Failed

curl -XGET localhost:9200 -k
curl: (52) Empty reply from server


Check for the following log in the output of docker-compose up

elasticsearch_1  | [2020-03-12T13:05:34,959][WARN ][c.f.s.h.SearchGuardHttpServerTransport] [Xrb6LcS] Someone (/ speaks http plaintext instead of ssl, will close the channel

Check for conflicting processes by running the below command (assuming 5888 is the port number)

sudo lsof -i:5888


  1. Try to close the conflicting processes. You can do this easily with fuser
    sudo apt-get install fuser

    Run the below command (assuming 5888 is the port number)

    fuser -k 58888/tcp

    Re-run docker-compose up and check if localhost:9200 shows up.’

  2. Use a docker-compose without SearchGuard. With this docker-compose, the ES doesn’t include SearchGuard, access to the Kibiter and Elasticsearch don’t require credentials. Re-run docker-compose up and check if localhost:9200 shows up.

Permission Denied


Can’t create indices in Kibana. Nothing happens after clicking create index.


Check for the following log in the output of docker-compose up

elasticsearch_1 |[INFO ][c.f.s.c.PrivilegesEvaluator] No index-level perm match for User [name=readall, roles=[readall], requestedTenant=null] [IndexType [index=.kibana, type=doc]] [Action [[indices:data/write/index]]] [RolesChecked [sg_own_index, sg_readall]]

or any type of 403 error.


This message generally appears when you try to create an index pattern but you are not logged in Kibana. Try logging in to Kibana (the login button is on the bottom left corner). The credentials used for login should be username:password admin:admin.

Empty Index

Indication and Diagnosis

Check for the following error after executing Micro Mordred using the below command (assuming git is the backend) --raw --enrich --panels --cfg ./setup.cfg --backends git
[git] Problem executing study enrich_areas_of_code:git, RequestError(400, 'search_phase_execution_exception', 'No mapping found for [metadata__timestamp] in order to sort on')


This error appears when the index is empty (here, git-aoc_chaoss_enriched index is empty). An index can be empty when the local clone of the repository being analyzed is in sync with the upstream repo, so there will be no new commits to ingest to grimoirelab.

There are 2 solutions to this problem:

  1. Disable the param latest-items by setting it to false.
    latest-items = false
  2. Delete the local clone of the repo (which is stored in ~/.perceval/repositories).

For more understaning:

The Git backend of perceval creates a clone of the repository (which is stored in ~/.perceval/repositories) and keeps the local copy in sync with the upstream one. This clone is then used to ingest the commits data to grimoirelab.

Grimoirelab periodically collects data from different data sources (in this specific case, a git repository) in an incremental way. A typical execution of grimoirelab for a git repository consists of ingesting only the new commits to the platform.

These commits are obtained by comparing the local copy with the upstream one, thus if the two repos are synchronized, then no commits are returned and hence Index will be empty. In the case where all commits need to be extracted even if there is already alocal clone, latest-items param should be disabled. Another option is to delete the local clone (which is stored at ~/.perceval/repositories), and by doing so the platform will clone the repo again and extract all commits.

Low File Descriptors


Cannot open localhost:9200 in browser, shows Secure connection Failed

curl -XGET localhost:9200 -k
curl: (7) Failed to connect to localhost port 9200: Connection refused


Check for the following log in the output of docker-compose up

elasticsearch_1  | ERROR: [1] bootstrap checks failed
elasticsearch_1  | [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]


  1. Increase the maximum File Descriptors (FD) enforced. You can do this by running the below command.
    sysctl -w fs.file-max=65536

    To set this value permanently, update /etc/security/limits.conf content to below. To verify after rebooting, run

    sysctl fs.file-max
    elasticsearch   soft    nofile          65536
    elasticsearch   hard    nofile          65536
    elasticsearch   memlock unlimited
  2. Override ulimit parameters in the Elasticsearch docker configuration. Add the below lines to Elasticsearch service in your compose file to override the default configurations of docker.
      soft: 65536
      hard: 65536

Rate Limit Exhausted


See error message RuntimeError: Rate limit exhausted.; 3581.0 seconds to rate reset


Enable the sleep-for-rate parameter. It increases rate by sleeping between API call retries.

sleep-for-rate = true
sleep-time = 300

No Swap Space


While composing docker , NO SWAP SPACE would be displayed.


Edit the /etc/default/grub file with sudo previleges and restart the system.

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
sudo update-grub

SSL error


localhost:9200 refuses connection error.


Retrying (Retry(total=10,connected=21,read=0,redirect=5,status=None)) after connection broken by 
'SSLError(SSLError{1,'[SSL: WRONG_VERSION_NUMBER] wrong version number {_ssl.c:852}'},)': /


Change https to http in the setup.cfg file if you are using the Elasticsearch without the SearchGuard. See defining-the-es-configurations.

url = http://localhost:9200

url = http://localhost:9200

Cloc installation


: [Errno 2]No such file or directory : 'cloc': 'cloc'


Execute the following command to install cloc (more details are available in the Graal repo).

sudo apt-get install cloc

Incomplete data


Not all the data is being retrieved when rebuilding an index - only from a point in time forward.


After a rebuild of git-based indices you are not receiving a full dataset as expected, but only from the date of the re-index forward. That data is complete, but anything prior to that is missing.


The setup.cfg file has an option under the Git configuration section: latest-items = true - set this to latest-items = false to pull in all data from the beginnning. Once this has been processed, remember to set it back to latest-items = true!

Directory Not Found


While you are running the cocom backend with micro-mordred, you might receive an error log of [Errno 2] No such file or directory: '/tmp/worktrees/grimoirelab-toolkit-git'. Encountered this error while setting up grimoirelab using source code and docker method.


The cocom backend would require worktrees. The micro-modred by default will attend to reach a location at <worktrees-path>/grimoirelab-toolkit-git.


You can create the directory manually:

  • make sure you installed cloc (see chaoss/grimoirelab-graal/README)
  • create two directory mkdir /somepath and mkdir /somepath/grimoirelab-toolkit-git
  • use /somepath/ as the worktree-path in setup.cfg’s [cocom] section. (see how to configure cocom in chaoss/grimoirelab-sirmordred/README)
  • rerun the command python --raw --enrich --cfg ./setup.cfg --backends git cocom
