--- title: "CMDB" canonical: https://harmony.io/platform/asset-management/cmdb --- # CMDB A configuration management database filled from the systems that already know your fleet, with people, devices, apps, tickets and services on one relationship map. ## A CMDB kept current by sync, not by hand Every person, device, application, ticket and service on one relationship map, filled from the systems already watching your environment. ## What is a CMDB? A configuration management database (CMDB) records the things IT supports and how they relate: which devices a person holds, which applications they use, which services depend on what, and which tickets touch each one. Most CMDBs fail on upkeep. Reconciled by hand each quarter, they are out of date before anyone reads them. [What is a CMDB?](https://harmony.io/insights/what-is-a-cmdb) covers the concept in depth. Harmony fills its CMDB from sync instead. Devices come from MDM, security status from EDR, people and departments from the identity provider and HRIS, network gear from Cisco Meraki and Juniper Mist, and peripherals from discovery on the endpoint. When a device appears in both a manual import and an MDM, the MDM record wins. The relationship map links requests, agents, assets, applications, contracts, people and services. Start from anyone or anything: an employee shows their laptops, monitors and peripherals, their applications, their manager and the tickets they raised. ## A CMDB your service desk can rely on - **Relationship map:** Requests, agents, assets, applications, contracts, people and services, linked and explorable from any starting point. - **Business services:** Define services and link the applications behind them. - **Synced configuration items:** Model, serial, OS, CPU, storage, battery health, disk encryption, MDM and compliance status, EDR status and last seen for every device. - **People context:** Each asset joined to its holder and their department, with the former assignee kept when it changes hands. - **Parent and child assets:** Peripherals linked to the device they connect to, inheriting its owner. - **Activity log:** Every change recorded with its source: a user action, system event, MDM sync, automation or discovery. - **Source precedence:** MDM data supersedes manually imported records, so an import never overwrites what a device reports about itself. - **CSV import:** Up to 1,000 rows per file for assets no connected system reports. ## How the CMDB stays current **Trigger:** A device enrolls or changes hands, an EDR agent goes missing, or an employee joins, moves or leaves. 1. **Connect the sources** - MDM, EDR, identity, HR and network systems sync into Harmony, so nothing is typed in by hand. 2. **Link the records** - Assets join to people, people to applications and tickets, and applications to services and contracts. 3. **Keep it current** - Every sync updates the record and writes the change, with its source, to the activity log. 4. **Act on gaps** - Agents find unassigned devices, employees without a device, missing EDR and unencrypted disks, and open the work before anyone files a ticket. **Outcome:** A CMDB that is rebuilt from source all the time, so the agents and the team can trust it. ## Mammoth Brands answers device questions without the device Because the CMDB pulls from Intune, Kandji, CrowdStrike and Microsoft Entra ID, the agent answers questions the Mammoth Brands team previously couldn't answer without the machine in hand. Marce Ayala's advice to IT leaders: insist on a CMDB that works out of the box and integrates with the major platforms - IdP, MDM, EDR. > The bot was able to step in and say, hey, I see that your battery actually needs to be replaced. And that's information that we wouldn't have unless we actually got the machine, ran a diagnostic, took a look at it. > > - Marce Ayala, Senior Manager, IT Infrastructure, Mammoth Brands ## Agents that close the gaps the CMDB finds - [Unassigned Assets](https://harmony.io/agents/unassigned-assets) - [Employees with No Assigned Assets](https://harmony.io/agents/employees-with-no-assigned-assets) - [Asset Activity Detection](https://harmony.io/agents/asset-activity-detection) - [EDR Status Discovery](https://harmony.io/agents/edr-status-discovery) - [Unencrypted Assets](https://harmony.io/agents/unencrypted-assets) - [Asset Ownership Confirmation](https://harmony.io/agents/asset-ownership-confirmation) ## Configuration data from every system that has it - **MDM: **[Jamf Pro](https://harmony.io/integrations/jamf-pro), [Microsoft Intune](https://harmony.io/integrations/microsoft-intune), [Kandji](https://harmony.io/integrations/iru-kandji), [JumpCloud](https://harmony.io/integrations/jumpcloud), [NinjaOne](https://harmony.io/integrations/ninjaone), [Addigy](https://harmony.io/integrations/addigy) - **EDR: **[CrowdStrike](https://harmony.io/integrations/crowdstrike), [SentinelOne](https://harmony.io/integrations/sentinelone), [Microsoft Defender for Endpoint](https://harmony.io/integrations/microsoft-defender-for-endpoint) - **Identity and HR: **[Okta](https://harmony.io/integrations/okta), [Microsoft Entra ID](https://harmony.io/integrations/microsoft-entra-id), [HiBob](https://harmony.io/integrations/hibob), [Workday](https://harmony.io/integrations/workday) - **Network: **[Cisco Meraki](https://harmony.io/integrations/cisco-meraki), [Juniper Mist](https://harmony.io/integrations/juniper-mist) ## FAQ ### What is CMDB software? Software that records the configuration items IT supports, such as devices, applications, services and people, and how they relate, so incidents, changes and requests start from an accurate picture. ### How is Harmony's CMDB kept up to date? By sync. MDM, EDR, identity, HR and network systems update the records continuously, every change is logged with its source, and MDM data takes precedence over manual imports. ### What does the relationship map show? Requests, agents, assets, applications, contracts, people and services, and the links between them. Select any record, such as an employee, to see their devices and peripherals, applications, manager and tickets. ### Which systems feed the CMDB? MDM platforms such as Jamf Pro, Microsoft Intune and Kandji, EDR such as CrowdStrike, SentinelOne and Microsoft Defender for Endpoint, identity and HR systems such as Okta, Microsoft Entra ID, HiBob and Workday, and network gear from Cisco Meraki and Juniper Mist. ### Can we add assets that no system reports? Yes. CSV import takes up to 1,000 rows per file. If an MDM later reports the same device, the MDM record supersedes the imported one.
