Agents is disconnected

[Henrique Avelino]

Hi

After reboot Wazuh-Manager Server, 90% of the agents are disconnected.

In /var/ossec/logs/ossec.log I have a lot of logs like this:

2024/04/11 00:58:38 wazuh-remoted: WARNING: Package dropped. Could not append data into buffer.

How Can I fix it?

[Henrique Avelino]

I need to fix this issue ASAP.

Hi Henrique,

First, let's verify that both the manager and the agent are on the latest available version (4.7.3), as we have addressed concurrency and performance issues in previous versions.

Next, there are two common causes for seeing these messages:

1. An agent disconnected while the manager had pending data to send to it. In this case, such data is the shared configuration. Don't worry, the manager will try to deliver the configuration again when the agent connects back.
2. There are performance issues in the network that slow down the transmission, to the point where the sending buffer fills up.

To diagnose the problem, I recommend the following actions:

1. Enable debug mode for wazuh-remoted: add "remoted.debug=1" to /var/ossec/etc/local_internal_options.conf, and restart the manager.

If the issue is the second one mentioned, we would see logs like this:

wazuh-remoted: DEBUG: Not enough buffer space. Retrying... [buffer_size=..., used=..., msg_size=...

2. Query the wazuh-remoted statistics through the API using:

curl -XGET -H "Authorization: Bearer $YOUR_JWT_TOKEN" https://localhost:55000/manager/daemons/stats?daemons_list=wazuh-remoted

This will provide insights into the performance of wazuh-remoted and help identify any potential bottlenecks or issues.

Hope it helps. Best regards,

Vikman

Hi Henrique,

Thank you for sharing the logs. Based on the information provided:

1. Firstly, it's crucial to ensure that both the manager and agents are running on the latest available version (4.7.3).

2. It appears that the manager is attempting to send data to the agents at a rate faster than they can receive. This can lead to package drops and warnings about the inability to send files to certain agents. To address this, you can diagnose the issue further using netstat and the API call you made. Additionally, I recommend extending the buffer size to 512 KiB to see if it improves the situation. You can do this by setting remoted.send_buffer_size to 524288 in the local_internal_options.conf file and then restarting the manager. (Refer Internal configuration).

3. Regarding the SSL certificate problem encountered with the API call, it seems that you're using a self-signed certificate, which is the default setup. To bypass the SSL certificate verification, you can simply add the -k option to your curl command. This will allow the API call to proceed without validating the SSL certificate. For more details, you can refer to the documentation here: Wazuh API - Getting Started.

This situation typically indicates either a manager overload or network congestion.

Hope this helps,

Best.

1. Yes, manager and agents are running on version 4.7.3

2. I still need to do this

3. Now it works:
root# curl -k -XGET -H "Authorization: Bearer Token_xxx" https://localhost:55000/manager/daemons/stats?daemons_list=wazuh-remoted
{"data": {"affected_items": [{"uptime": "2024-04-11T12:15:57+00:00", "timestamp": "2024-04-11T18:39:00+00:00", "name": "wazuh-remoted", "metrics": {"bytes": {"received": 6342281674, "sent": 2034706951}, "keys_reload_count": 11, "messages": {"received_breakdown": {"control": 337440, "control_breakdown": {"keepalive": 332380, "request": 0, "shutdown": 57, "startup": 5003}, "dequeued_after": 26283, "discarded": 0, "event": 6727996, "ping": 0, "unknown": 141}, "sent_breakdown": {"ack": 336801, "ar": 179165, "discarded": 1578, "request": 0, "sca": 8, "shared": 4980259}}, "queues": {"received": {"size": 131072, "usage": 0}}, "tcp_sessions": 217}}], "total_affected_items": 1, "total_failed_items": 0, "failed_items": []}, "message": "Statistical information for each daemon was successfully read", "error": 0}

Thanks.

Hi Henrique,

Thank you for providing the diagnostic data. Upon analyzing the information:

If we delve into these data, we find that the service was active for 162 minutes (from uptime to timestamp). Adding up the events (6727996) plus the control messages (337440), we get 726.9 messages/second, which is quite acceptable, especially considering that the usage of the receiving queue is 0 (no stress on message input).

However, there are three things that catch my attention:

1. Despite the common receiving queue being empty, one or more sending queues (one per agent) are full. This could indicate some communication issue in the manager → agent direction.
2. There is a relatively high number of dequeued_after messages, which are messages processed after the agents have disconnected. This suggests there may be a lot of connection/disconnection activity.
3. There is an unusually high number of shared messages sent. These correspond to shared configuration (etc/shared). Out of curiosity, have you copied any relatively large extra files into that folder?

Regarding netstat, it might shed light on any network-level issues:

An example:

$ netstat -tn | grep -E "^Proto|:1514 "

Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 192.168.64.6:1514 192.168.64.1:49292 ESTABLISHED

Normally, both Recv-Q and Send-Q should have a value of 0 or very low. This, combined with the idea of increasing the size of the sending queues, will likely bring us closer to the root cause of this issue.

Let me know if you need further assistance or clarification on any of these points.

Best regards,

Vikman
