Ensure 24/7 uptime with server availability monitoring

OpManager's server availability monitoring ensures your servers remain operational through constant polling using ICMP, SNMP, WMI, and TCP protocols. Real-time monitoring of server availability is crucial to ensure quick responses to I/O requests and maintain seamless connectivity for end-users. Additionally, you can track packet loss and response time to identify and address latency issues originating from the server.

OpManager's high availability monitoring minimizes downtime and ensures consistent network availability by tracking fault resolution metrics such as Mean Time to Repair (MTTR) and Mean Time Between Failures (MTBF).

Monitor, restart, terminate the services/processes in few clicks

In addition to monitoring system-level services like HTTP, LDAP, and SMTP, OpManager also monitors Windows Services such as Alerter, FTP, Net Logon, DHCP Server, IAS, Print Spooler, and more. If a service becomes dormant, OpManager's server monitoring enables automatic configurations to restart the service or even the server itself. Additionally, OpManager supports adding monitors for custom services running on TCP ports.

OpManager discovers all processes running on your servers and provides detailed information, including Process ID, Process Name, Process Path, and Process Arguments. With Process Templates, you can easily discover, manage, and set thresholds across multiple servers from a single window. The Remote Process Diagnostics feature offers a quick overview of top processes by CPU and memory utilization, allowing you to remotely terminate problematic processes with ease.

Get a glimpse of your server performance with intuitive dashboards and graphs

Prevent server performance issues with OpManager's threshold-based monitoring. Gain in-depth insights into server health and performance through OpManager's intuitive dashboards and graphs, all within a single window. You can even create custom widgets to keep a close watch on critical server performance metrics such as CPU utilization, memory utilization, and storage, offering a quick glimpse of these metrics on the go.

Obtain a comprehensive view of your servers' status by creating custom server monitoring dashboards, such as Windows Server Monitoring Dashboards, Linux Server Monitoring Dashboards, or Server Performance Monitoring Dashboards, tailored to your needs.

Employ severity-based alerting to automate network and server troubleshooting

Leverage OpManager's server monitoring to identify and resolve server faults with active alerting and automated troubleshooting capabilities. OpManager uses severity-based alerting to notify you of threshold violations, enabling quick responses to network faults. Notification modes include SMS, email, Slack messages, ticket logs, web alarms, and more.

Upon receiving fault notifications, network admins can automate L1 and L2 troubleshooting by running designated scripts or workflows. Alternatively, they can perform manual root cause analysis or utilize NetPath analysis for deeper insights.

Avert potential network threats with security and event logs monitoring

OpManager helps detect attempted security breaches on your application servers by processing Windows Security Event Logs. It can identify incidents such as failed logins due to incorrect passwords, account lockouts, unauthorized attempts to access secure files, and tampering with security logs.

In addition to security logs, OpManager monitors application logs with preconfigured rules for Exchange, IIS, MS SQL, and ISA servers. It also supports monitoring system logs and other event logs, providing comprehensive log management and security insights.

Unified server monitoring across vendors and entities

Experience end-to-end server monitoring in a multi-vendor, hybrid environment from OpManager's unified console.

Multi-vendor server monitoring

Monitor and manage your multi-vendor environment, including physical and virtual servers, effortlessly from a unified console with OpManager. Seamlessly manage physical servers from leading vendors like Dell, HP, and IBM, as well as virtual servers from platforms such as VMware, Hyper-V, Nutanix, and Xen.

Domain controller monitoring

Oversee the health of the domain controller in real-time with the information gathered from monitoring domain services (DS) and system resource usage. You can even assign notification profiles to domain controllers so that when any of the monitors fail, you'll be alerted in an instant.

Remote server monitoring

Monitor and manage your remote servers with OpManager's centralized monitoring interface for SNMP/Redfish API-based IPMI devices. Take a quick look on the IPMI devices' hardware health in the form of graphs. You can also choose to export the data for further analysis.
