You can create jobs in OpsRamp to scan and view the missing patchesfor a version. An internal job starts automatically after you install the agent in the devices and provides you a list of missing patches for that device. You can look into the steps from 1 to 3 in the preceding diagram, to understand the Patch Scan process.Patch approvalAfter you get the missing patches, you can approve the relevant ones for installation. All security and critical whitelisted patches are approved automatically after you enable Auto-Approve. You can manually approve a patch or rate patches With a whitelist, you can approve patches globally by selecting several devices at a time. OpsRamp captures all patch approvals for audit trails. OpsRamp also sends notifications after approving the patches. You can look into step 4 in the preceding diagram, to understand the Patch Approval process. The approved ID list is sent to the agent for installation. The patch install schedule can help configure the installation time and the source for the patches to be installed. Patch configurationOpsRamp lets you configure patches in your devices depending on the Approval Type, Reboot Options, and Patching Schedule. Once configured, you can click the Run Now option to install the patches.Patch on-demandYou can click the Run Now option in the Patch Configuration to install the patching.Patch notificationsYou can notify your users in the event of any Patch configuration or Patch Approval. OpsRamp also lets you select users to receive notifications after performing an action in Patch Management.Patch featuresPatch feedA patch feed is a source of published information. Patch feed refers to a source of patch information with all the available attributes of the patch. You can obtain a patch feed from an OS vendor, a software package provider or from a partner who provides additional qualifications or insights into the published packages and manages it.A typical patch feed provides the following information:The patch details such as patch name, patch ID, severity, OS Version, and release datePatch rating, if the feed provider rates the patch.CVE ID, if the feed provider enters the ID.Patch baselineA Patch Baseline can help you elucidate the approved patches for your resources.Patch complianceYou can configure patch compliance check jobs to track the compliance of selected devices or device groups against the configured baselines. Patch compliance check job is automatically computed after every run of the patch scan on the device.Patch ratingPatch ratings can help you prioritize the patch update process.Patch management widgetsOpsRamp offers the following widgets in the Dashboard that can provide you a snapshot of the current status of the patches in your Windows and Linux devices.Patch Compliance – Lets you view the compliance status of a set of devices for a specific baseline.Patch Pending Approvals – Lets you view the number of patches that are pending for approval from your end.Patch Status – Devices count categorized by patch installed, pending for installation of approved critical and security patches. The widget displays data as per the most recent patch scan conducted within the last 30 days.ScenariosInstalling the latest critical patchesAfter you identify the latest patches, you can whitelist the patches either using the UI or the OpsRamp Patch Feed API.
