Data sources

Data source	Description	API endpoint	Collector service name	Devo table	Available from release
Get User Activity Log List	Customers can monitor changes in their Cloud WAF applications using the Activity log. Any change in the configuration is logged in the Activity Log, including the time and the user that performed the change.	`v1/userActivityLogs/reports/`	`user_activity`	`waf.radware.api.user_activity`	v1.0.0
Get Security Events List	Security events are the events reported by WAF when an attack is detected. This allows user visibility to the protected traffic, refinement of false positives, and detailed explanations of security attacks.	`mgmt/monitor/reporter/reports-ext/APPWALL_REPORTS`	`security_events`	`waf.radware.api.security_event`	v1.0.0

Minimum configuration required for basic pulling

Although this collector supports advanced configuration, the fields required to retrieve data with basic configuration are defined below.

This minimum configuration refers exclusively to those specific parameters of this integration. There are more required parameters related to the generic behavior of the collector. Check setting sections for details.

Setting	Details

Setting	Details
username	The username for the Radware API. To find out how to get it, see the Vendor Setup guide.
password	The password for the Radware API. To find out how to get it, see the Vendor Setup guide.

See the Accepted authentication methods section to verify what settings are required based on the desired authentication method.

Accepted authentication methods

Authentication method	username	password

Authentication method	username	password
token	status:REQUIRED	status:REQUIRED

Run the collector

Once the data source is configured, you can either send us the required information if you want us to host and manage the collector for you (Cloud collector), or deploy and host the collector in your own machine using a Docker image (On-premise collector).

Collector services detail

This section is intended to explain how to proceed with specific actions for services.

Internal process and deduplication method

Data is collected by setting a start date and by pagination. To eliminate duplicates, the date of the last event sent to Devo and the ids of events with the same date are stored.

Devo categorization and destination

All events of this service are ingested into the table waf.radware.api.user_activity. This service has the following components:

Component	Description

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.

After a successful collector’s execution (that is, no error logs found), you will see the following log message:

INFO InputProcess::RadwarePuller(radware_input,12345,user_activity,predefined) -> Statistics for this pull cycle (@devo_pulling_id=1695715370653):Number of requests made: 1; Number of events received: 2; Number of duplicated events filtered out: 0; Number of events generated and sent: 2; Average of events per second: 0.580.

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:

Edit the configuration file.
Change the value of the initial_start_time_in_utc_value parameter to a different one.
Save the changes.
Restart the collector.

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.

Troubleshooting

This collector has different security layers that detect both an invalid configuration and abnormal operation. This table will help you detect and resolve the most common errors.

Collector operations

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

Initialization

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

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

2023-01-10T15:22:57.146    INFO MainProcess::MainThread -> Loading configuration using the following files: {"full_config": "config.yaml", "job_config_loc": null, "collector_config_loc": null}

2023-01-10T15:22:57.171 WARNING MainProcess::MainThread -> [WARNING] Illegal global setting has been ignored -> multiprocessing: False

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:

2023-01-10T15:23:00.788    INFO OutputProcess::MainThread -> DevoSender(standard_senders,devo_sender_0) -> Starting thread
2023-01-10T15:23:00.789    INFO OutputProcess::MainThread -> DevoSenderManagerMonitor(standard_senders,devo_1) -> Starting thread (every 300 seconds)
2023-01-10T15:23:00.790    INFO OutputProcess::MainThread -> DevoSenderManager(standard_senders,manager,devo_1) -> Starting thread
2023-01-10T15:23:00.842    INFO OutputProcess::MainThread -> global_status: {"output_process": {"process_id": 18804, "process_status": "running", "thread_counter": 21, "thread_names": ["MainThread", "pydevd.Writer", "pydevd.Reader", "pydevd.CommandThread", "pydevd.CheckAliveThread", "DevoSender(standard_senders,devo_sender_0)", "DevoSenderManagerMonitor(standard_senders,devo_1)", "DevoSenderManager(standard_senders,manager,devo_1)", "OutputStandardConsumer(standard_senders_consumer_0)",

By default, these information traces will be displayed every 10 minutes.

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

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

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 "2023-01-10 16:09:16.116750+00:00": 21 (elapsed 0.000 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 2023-01-10 16:09:16.116750+00:00.
21 events where sent to Devo between the last UTC checkpoint and now.
Those 21 events required 0.000 seconds to be delivered.

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
