GLPI Inventory

GLPI Inventory installer instructions?

A procedure is available here to help you configure GLPI Inventory.

What are the features of GLPI Inventory?

With GLPI Inventory, you can access advanced tools to manage your network. List of available tools:

• Network Discovery

• Network Inventory (SNMP)

• Data Collection

• Package Deployment

• VMware host remote inventory

---

What is the difference between "Network Discovery" and "Network Inventory"?

Discovery helps you identify the devices on your network. GLPI searches for responding IP addresses and adds them to your network inventory.

Network inventory uses the SNMP protocol to more precisely identify devices previously inventoried with network discovery.

---

Why are my devices showing up in the "Ignored Devices" section?

Devices that are ignored are placed in this section when they are "quarantined" to avoid cluttering the IT infrastructure with unnecessary or erroneous data.

The devices that may be found here are most often:

• Virtual machines (for companies that do not wish to inventory physical hardware).

• Personal devices of users scanned at their homes while teleworking (personal internet boxes, home printers, etc.).

• IP phones or small, unmanaged switches discovered on the network but deemed irrelevant.

---

My switch/router is correctly discovered, but the SNMP inventory is not reporting any ports. Why?

This problem generally occurs when the SNMP community is not properly configured. You can refer to this tutorial to guide you through configuring this task.

---

What is the impact of the Network Discovery task on the load of my server and network?

Indeed, network discovery can impact network and/or server load if it is oversized. Furthermore, the more simultaneous threads you allow, the heavier the load will be on the network and your server. You can configure this data in Administration > GLPI Inventory > General > General Configuration > Network Inventory.

---

Why do the GLPI agent logs tell me that the task is not supported?

If you want the GLPI agent to be able to use the tasks (data collection, network inventory, network discovery, package deployment, remote inventory of SNMP hosts (VMware)), these tasks must have been enabled during the agent installation.

---

What is the purpose of groups?

In GLPI Inventory, there are two types of groups:

• Dynamic group: This group is populated according to specific criteria (entity, location, OS, etc.) which can be combined. This group will be dynamically modified as the hardware evolves and according to changes in the criteria associated with it.

• Static group: Static groups consist of computers that you have manually configured.

When you create a task, you can deploy it to groups, making task management easier.

---

How many agents can a task put into preparation before execution?

When the Permit to re-prepare task after run option is enabled, GLPI puts the task into a waiting state before its next execution. A task cannot then exceed the limit of 500 agents.

---

Can the 500-agents limit be bypassed when re-preparing tasks?

To bypass this limitation, the concept of a preparation window must be used. Depending on how the automatic actions are launched, all the agents to be prepared will be prepared in batches of 500 per execution of the automatic action. To clarify, if the automatic agent preparation action named taskscheduler runs every minute, the task can only wake up a maximum of 500 x 60 = 30,000 agents in one hour (assuming no agent launches the task in the interval: if this is the case, the agents in question would be candidates for preparation again within the window).
