The Agents screen is accessible by logging into the Web Console and navigating to [Manage→DPOD Health→Agents].

DPOD agents are responsible for collecting data (either actively or passively) from monitored devices and storing it in the Store. This screen allows you to verify that the agents are up and running.

The screen shows two sections:

Agent Status - Showing the state of all the agents
Agent Processing Status- Showing streaming and memory consumption data

Agent Status

The Agent Status section of the screen is a set of 3 widgets, each displaying data related to a different set of DPOD Agents: Syslog, WS-M and Resources. The agents are monitored internally by a KeepAlive service. For a list of all system services, and an explanation on KeepAlive processing, see section on System Services Management.

Each agent is displayed in a colored box (see below). Click an agent's name to open its details in the Agent's Detail view.

The table below describes the details presented for each agent:

Detail	Description	Desired State
General Health Status	The general health status of the agent is relayed by the color of the box wrapping its details. Green – The agent is running and is ready to receive and store syslog messages (Keepalive checks were successful) Yellow – Syslog records or Keepalive checks did not arrived in the last 3 minutes OR number of dropped records is greater than 0. Red – Syslog records or Keepalive checks did not arrived in the last 10 minutes or more. Grey - Device/Service Resources agents only. No monitored devices were added yet, or device/service resource monitoring wasn't requested for any device (this status does not indicate any problem) Possible agent issues : Monitored device system time that is not synced with DPOD's system time could send Syslog record with "future" time that will cause the agent's health status to be Yellow or Red. The agent service is down - Syslog records and Keepalive records will be processed causing the agent's status to change to Yellow or Red. The Keepalive service is down - Syslog agent did not receive any records from monitored device, this will cause the agent's status to change to Yellow or Red.	Green - the agent is healthy.
Date / Time	The timestamp of the last successful record processed by the agent (Syslog record or Keepalive check). A delay of over a minute may suggest a performance problem. Note: It is important to verify that system time is time synced correctly when reading these values.	< 3 minutes
Msg. Rate	This is the total number of messages of all types (syslog, WS-M, and keepalive messages) processed by this agent in the last 10 minutes. Verify: That the number is greater than 1. If it isn’t, either agents are down or the network is down. For Syslog agents: the number should reflect the expected throughput of raw logs records received from all monitored devices in the last 10 minutes. For WS-M agents: If WS-M recording is enabled, the number should reflect the message throughput for the recording service/domain in 10 minutes. If this value is more than 500,000 consider redistributing traffic to other agents, in order to optimize performance You may redirect syslog traffic from one agent to another by assigning it to a domain a specific agent. For more details see Adding Monitored Gateways.	1 < value < 500,000 (if there are any monitored devices)
Dropped Msgs (For Syslog and WS-M agents)	This is the total number of syslog or WS-M messages that were sent from the monitored devices but were not processed by the DPOD agent in the last 10 minutes. Dropped messages usually indicate that the agent cannot keep up with the load, consider redistribution of traffic to other agents.	0

Agents processing status

The bottom of the screen displays the agents processing status graphs, which relay the state of processing agents.

Graph	Details	Desired State
Files Process Pending	The graph depicts the number of large payloads waiting to be processed. A value higher than 1000 indicates a high load on WS-M subscription. WS-M usage should be avoided until this folder is cleared by the system or you clear it manually.	Only a few files displayed
Channel Utilization	The graph depicts stream processing usage in percentage. Each colored graph denotes a different agent. Verify that all agents use less than 80% of their stream processing capacity. If usage goes above 80%, data coming in from agents might be lost. See how to Troubleshoot & Support the issue.	Under 80% for all agents
Agents Free Memory	The graph depicts the agents’ free memory over time, where each agent is denoted in a different color. When an agent's free memory is too low, you might encounter performance problems. See how to Troubleshoot & Support the issue.	Verify that each agent has at least 30-40 Mil free.

Agent's Detail View

When clicking an agent name on the Agent Status screen, DPOD opens the agent's details in a single-agent details view.

The Agent Details view is composed of 4 widgets (for syslog and WS-M Agents) or 3 widgets (for Resources Agents).

Agent Details

The agent details widget displays the following information for the agent:

Detail	Description
IP	The IP where this agent runs
DNS	The DNS of the agent (if set)
Port	The port the agent is listening on
Keepalive	On / Off state of the keepalive service for this agent
Dropped Msgs (10 mins)	How many messages were lost by the agent
Message Rate (10 min)	Number of messages handles by agent in the last 10 minutes
Newest Message	Timestamp of the latest message received on this agent

Recent Keep-Alive Messages

This widget displays a table with details of recent keep-alive messages received on this agent. Scanning this table for changes in frequency may help catching issues.

The following information is displayed for each message:

Column	Description
Device	The device emitting the message. Click on the device name to view the device in the Logs view.
Domain	The domain for this message
Category	Always montier-ka
Severity	Always debug
Time	Timestamp for the Keep-Alive message
Direction	N/A
Object Type	N/A
Object Name	N/A
Trans. ID	N/A
Client IP	This will always be the originating host so 0.0.0.0
Message	Keep-Alive message text.

Agent Statistics

Graph	Description
Message Rate (per sec)	This widget displays a graph of the number of messages per second going through this agent over the last 24 hours period
Dropped Syslog Messages	This graph shows the number of messages dropped by the agent. This value is cumulative , the agent will reset it to zero only after restart.
Channels Utilization	The graph depicts stream processing usage of the current agent in percentage.
Free Memory	The graph depicts the agent free memory over time.

Reporting Domains (24 hrs.)

This widget lists the domains reporting in the preceding 24 hours period.
The list may be used to identify that a device has dropped off the monitoring list.
