v1149+ Migration Tool for Unified Events

A change was introduced in how events are indexed and stored in version 1149 of the Sysdig platform.

Prior to this version, the three types of events were stored in three separate indexes, based on their different sources:

Alert events: stored in MySQL (alert_notifications table)
Custom events (from both the infrastructure components and any custom event integrations): stored in ElasticSearch (events_v1 index)
Policy events (from Sysdig Secure): stored in ElasticSearch (policy_event_v1 index)

With version 1149 , they will be combined in one index.

The Unified Events migration tool is delivered as a Docker container and is used to migrate events from multiple sources to a single source. When the migration and upgrade are complete, you manually terminate the migration tool.

Warning

It is highly recommended to run the migration tool BEFORE launching the upgrade to version 1149.

If you do not migrate before upgrading, you will lose visibility to old custom events in the Sysdig Monitor UI.

Prerequisites

You must be running Sysdig platform version 1091 . If your on-premises version is less than 1091, upgrade appropriately before running the migration tool.
Warning
It is highly recommended to follow upgrade best practices:
- Keep upgrades current
- Upgrade progressively without skipping versions, and
- Test upgrades in a non-mission-critical or staging environment before rolling in to production.
The migration tool container must have network visibility to the data sources used for re-indexing: MySQL and ElasticSearch.
Launch migration before upgrading to version 1149.

Where to Find the Tool

The migration tool is provided as a containerized JavaApp on a public Quay repository. The Kubernetes and Replicated steps below give the precise location.

Running the Migration

Since events are constantly being generated, the migration tool executes the migration in batches. After each batch is indexed, the tool will try to fetch the next one, with a predefined cutoff.

When the tool finishes indexing old events and has begun to wait for new ones, the Sysdig application upgrade can be launched. In the background, during the upgrade, the tool ensures that incoming events in old indexes are properly reindexed to the new unified table.

The migration steps are:

Run the container image.
Monitor the logs to see when old events have finished migrating.
Launch the upgrade.
Terminate the migration tool manually.

Depending on your environment, follow the steps for Kubernetes or Replicated.

Kubernetes Steps

1. Run the Container Image (K8s)

Run the following command:

kubectl -n sysdigcloud create -f MIGRATION_TOOL_SPECS.yaml

Where MIGRATION_TOOL_SPECS is defined as follows.

(You can obtain the .yaml template from GitHub repository or copy/paste it from this document. )

2. Watch the Migration Logs (K8s)

Run a command to tail the logs so you can see when old events have finished migrating:

kubectl -n sysdigcloud logs -f sysdig-event-migration

The tool will begin to migrate old events:

2018-07-25 09:58:50.806  INFO 7 --- [           main] c.s.m.events.AlertEventMigration         : Indexed 250 events; latest id is 133932

When complete, it will be begin to check for new events in 1-minute intervals:

2018-07-25 09:59:44.206  INFO 7 --- [           main] c.s.m.events.AlertEventMigration         : No more alert_event to migrate...

At this point you can launch the upgrade to version 1149. The migration tool continues to run.

3. Upgrade the Sysdig Platform (K8s)

Check the Release Notes ( Changelog Overview ).Changelog Overview

Follow the process to Basic Upgrade Kubernetes Installations.

During upgrade, the tool will check periodically for new events.

4. Terminate the Migration Tool (K8s)

When the Sysdig platform update is complete, leave the migration tool running for at least 3 minutes.

To verify that the process is complete, check in the logs that custom events are no longer migrating. Sample output:

2018-07-25 10:00:49.484  INFO 7 --- [           main] com.sysdig.services.MigrationService     : --- Executing customEventMigration ---
2018-07-25 10:00:49.607  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : Starting from id 0
2018-07-25 10:00:49.882  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : Event count to be migrated: 0
2018-07-25 10:00:50.148  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : No more custom_event to migrate...

Then terminate the migration tool by running the following command:

kubectl -n sysdigcloud delete -f {migration_tool_specs}.yaml

Migration and upgrade are complete.

If necessary, check the Troubleshooting tips, below.

Replicated Steps

If your environment is airgapped, you need to create an "image" of the migration tool that can be used on an airgapped install. Otherwise, proceed with 1. Run the Container Image (Replicated)

Prerequisite for Airgapped Environments

Pull the image onto a host that has access to the Internet:

docker pull quay.io/sysdig/onprem_migration:combined-events_0.1.0_1091-1149

Save the downloaded image to a TAR file:

docker save -o migrate.tar quay.io/sysdig/onprem_migration

Move the image TAR to the airgapped machine and deploy the image:
```
docker load -i migrate.tar
```

Continue with the Replicated steps, below.

1. Run the Container Image (Replicated)

Ensure that the container has network visibility to the MySQL and ElasticSearch components.
Run the migration tool container on a Coordinating Replicated Node, and run the container using the private addresses of data source endpoints.
Note
The data source endpoints can be found on the Replicated Dashboard, in Cluster settings.
Other parameters, such as DB usernames, can be found in the Settings section of the Replicated Dashboard console.
NOTE: The MySQL password was set when the Sysdig back end was installed (using Replicated). The administrator needed to save and remember the DB passwords that were set, as they are not visible in the Replicated console.

Execute the following Docker run command, providing the values described in the Appendix - Migration Tool Container Parameters

In Docker command format:

docker run -d --name sysdig-event-migration -e DB_ENDPOINT=10.111.0.1 -e DB_CONNECTION_TIMEOUT=4000 -e DB_SOCKET_TIMEOUT=12000 -e DB_USER=root -e DB_PASSWORD=<password> -e BATCH_SIZE=350 -e ES_ENDPOINT=http://10.111.0.1 -e ALERT_EVENTS=true -e CUSTOM_EVENTS=true -e POLICY_EVENTS=true -e REPAIR_MODE=false -e ONPREM=true quay.io/sysdig/onprem_migration:combined-events_0.1.0_1091-1149

2. Watch the Migration Logs (Replicated)

Run a command to tail the logs so you can see when old events have finished migrating:

docker logs -f sysdig-event-migration

The tool will begin to migrate old events:

2018-07-25 09:58:50.806  INFO 7 --- [           main] c.s.m.events.AlertEventMigration         : Indexed 250 events; latest id is 133932

When complete, it will be begin to check for new events in 1-minute intervals:

2018-07-25 09:59:44.206  INFO 7 --- [           main] c.s.m.events.AlertEventMigration         : No more alert_event to migrate...

At this point you can launch the upgrade to version 1149. The migration tool continues to run.

3. Upgrade the Sysdig Platform (Replicated)

Check the Release Notes ( Changelog Overview ).Changelog Overview

Follow the process to Upgrade Replicated Installations.

During upgrade, the tool will check periodically for new events.

Note

In Replicated, the upgrade requires ElasticSearch and MySQL servers to be restarted, so you will experience connection loss during upgrade. The migration tool is designed to handle this gracefully, so connection loss WARN messages in logs are expected and not a problem with the migration.

Replicated logger output (note the WARN messages):

4. Terminate the Migration Tool (Replicated)

When the Sysdig platform update is complete, leave the migration tool running for at least 3 minutes.

To verify that the process is complete, check in the logs that custom events are no longer migrating.

Sample output:

2018-07-25 10:00:49.484  INFO 7 --- [           main] com.sysdig.services.MigrationService     : --- Executing customEventMigration ---
2018-07-25 10:00:49.607  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : Starting from id 0
2018-07-25 10:00:49.882  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : Event count to be migrated: 0
2018-07-25 10:00:50.148  INFO 7 --- [           main] c.s.m.events.CustomEventMigration        : No more custom_event to migrate...

Then terminate the migration tool, by running the following command:

docker stop sysdig-event-migration
docker rm sysdig-event-migration

Migration and upgrade are complete.

If necessary, check the Troubleshooting tips, below.

Troubleshooting

In rare cases, migration errors can occur due to incorrect container configuration, network latency, or temporary cluster overload.

Note

Temporary connection-loss errors in Replicated are expected and are not migration errors, as described in Upgrade the Sysdig Platform (Replicated)

Migration Startup Errors

Startup errors are normally due to incorrect environment variable settings.

Check URL endpoints, passed credentials, flags, etc.

Migration Process Errors

If you were able to run migration successfully, it functioned for a while, and then began to experience errors, this is most likely caused by network latency or cluster overload. In these cases, the migration tool will try to reduce the pressure on the cluster by reducing batch size exponentially, with a predefined backoff wait time.

Ultimately, if events cannot be indexed, the migration tool will skip the issued batch and try to index the next batch. Information about the failed batch will be stored in the MySQL table utility_metadata.

Temporary Errors

If errors are only temporary, simply proceed with Running the Migration Steps.
When migration is complete, run the migration container again with the -e REPAIR_MODE=true parameter. This will index all failed migrations stored in the MySQL table utility_metadata.

Continuous Errors

At this point, abort the migration attempt. Check the number of errors to decide how to proceed.

To do so, check the MySQL table with:

SELECT COUNT(*) FROM utility_metadata WHERE metadata_id LIKE 'failure-%';

LOW Error Count (0 - 1000)

Try to identify why errors started (i.e. temporary cluster overload), resolve the problem and re-run the migration.
When migration is complete, run the migration container again with the -e REPAIR_MODE=true parameter. This will index all failed migrations stored in the MySQL table utility_metadata.

HIGH Error Count (10,000+)

Try to identify why errors started (i.e. temporary cluster overload), resolve the problem, and RESET the migration progress completely by clearing all content from the MySQL table utility_metadata.
(e.g. DELETE FROM utility_metadata;)
Repeat Running the Migration Steps.
