Overview

Logs generated by most AWS services (CloudTrail, VPC Flows, Elastic Load Balancer, etc.) are exportable to a blob object in S3. Many other 3rd party services have also adopted this paradigm so it has become a common pattern used by many different technologies. Devo Professional Services and Technical Acceleration teams have a base-collector code that will leverage this S3 paradigm to collect logs and can be customized for different customer's different technology logs that may be stored in S3.

This documentation will go through setting up your AWS infrastructure for our collector integration to work out of the box:

  • Sending data to S3 (this guide uses CloudTrail as a data source service)

  • Setting up S3 event notifications to SQS

  • Enabling SQS and S3 access using a cross-account IAM role

  • Gathering information to be provided to Devo for collector setup

General architecture diagram

Requirements

  • Access to S3, SQS, IAM, and CloudTrail services

  • Permissions to send data to S3

  • Knowledge of log format/technology type being stored in S3

Create S3 bucket and set up data feed (CloudTrail example) 

Check this article for a setup configuration example.

Run the collector

Verify data collection

Once the collector has been launched, it is important to check if the ingestion is performed in a proper way. To do so, go to the collector’s logs console.

This service has the following components:

Component

Description

Setup

The setup module is in charge of authenticating the service and managing the token expiration when needed.

Puller

The setup module is in charge of pulling the data in a organized way and delivering the events via SDK.

Setup output

A successful run has the following output messages for the setup module:

Puller output

A successful initial run has the following output messages for the puller module:

Note that the PrePull action is executed only one time before the first run of the Pull action.

Restart the persistence

This collector uses persistent storage to download events in an orderly fashion and avoid duplicates. In case you want to re-ingest historical data or recreate the persistence, you can restart the persistence of this collector by following these steps:

  1. Delete and Re-DO the collector with new ID number

The collector will detect this change and will restart the persistence using the parameters of the configuration file or the default configuration in case it has not been provided.

Note that this action clears the persistence and cannot be recovered in any way. Resetting persistence could result in duplicate or lost events.

Collector operations

This section is intended to explain how to proceed with specific operations of this collector.

Verify collector operations

The initialization module is in charge of setup and running the input (pulling logic) and output (delivering logic) services and validating the given configuration.

Events delivery and Devo ingestion

The event delivery module is in charge of receiving the events from the internal queues where all events are injected by the pullers and delivering them using the selected compatible delivery method.

A successful run has the following output messages for the initializer module:

INFO OutputProcess::SyslogSenderManagerMonitor(standard_senders,sidecar_0) -> Number of available senders: 1, sender manager internal queue size: 0
INFO OutputProcess::SyslogSenderManagerMonitor(standard_senders,sidecar_0) -> enqueued_elapsed_times_in_seconds_stats: {}

INFO OutputProcess::SyslogSenderManagerMonitor(internal_senders,sidecar_0) -> Number of available senders: 1, sender manager internal queue size: 0
INFO OutputProcess::SyslogSenderManagerMonitor(internal_senders,sidecar_0) -> enqueued_elapsed_times_in_seconds_stats: {}

INFO OutputProcess::SyslogSenderManagerMonitor(internal_senders,sidecar_0) -> Internal - Total number of messages sent: 1, messages sent since "2022-06-28 10:39:22.516313+00:00": 1 (elapsed 0.019 seconds)

Sender services

The Integrations Factory Collector SDK has 3 different senders services depending on the event type to delivery (internal, standard, and lookup). This collector uses the following Sender Services:

Sender Services

Description

internal_senders

In charge of delivering internal metrics to Devo such as logging traces or metrics.

standard_senders

In charge of delivering pulled events to Devo.

Sender statistics

Each service displays its own performance statistics that allow checking how many events have been delivered to Devo by type:

Logging trace

Description

Number of available senders: 1

Displays the number of concurrent senders available for the given Sender Service.

sender manager internal queue size: 0

Displays the items available in the internal sender queue.

This value helps detect bottlenecks and needs to increase the performance of data delivery to Devo. This last can be made by increasing the concurrent senders.

Total number of messages sent: 44, messages sent since "2022-06-28 10:39:22.511671+00:00": 21 (elapsed 0.007 seconds)

Displayes the number of events from the last time and following the given example, the following conclusions can be obtained:

  • 44 events were sent to Devo since the collector started.

  • The last checkpoint timestamp was 2022-06-28 10:39:22.511671+00:00.

  • 21 events where sent to Devo between the last UTC checkpoint and now.

  • Those 21 events required 0.007 seconds to be delivered.

By default these traces will be shown every 10 minutes.

Check memory usage

To check the memory usage of this collector, look for the following log records in the collector which are displayed every 5 minutes by default, always after running the memory free process.

  • The used memory is displayed by running processes and the sum of both values will give the total used memory for the collector.

  • The global pressure of the available memory is displayed in the global value.

  • All metrics (Global, RSS, VMS) include the value before freeing and after: previous -> after freeing memory

INFO InputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(34.50MiB -> 34.08MiB), VMS(410.52MiB -> 410.02MiB)
INFO OutputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(28.41MiB -> 28.41MiB), VMS(705.28MiB -> 705.28MiB)

Differences between RSS and VMS memory usage:

  • RSS is the Resident Set Size, which is the actual physical memory the process is using

  • VMS is the Virtual Memory Size which is the virtual memory that process is using

Enable/disable the logging debug mode

Sometimes it is necessary to activate the debug mode of the collector's logging. This debug mode increases the verbosity of the log and allows you to print execution traces that are very helpful in resolving incidents or detecting bottlenecks in heavy download processes.

  • To enable this option you just need to edit the configuration file and change the debug_status parameter from false to true and restart the collector.

  • To disable this option, you just need to update the configuration file and change the debug_status parameter from true to false and restart the collector.

For more information, visit the configuration and parameterization section corresponding to the chosen deployment mode.
