Server and Application Monitoring
Agentless monitoring of operating systems, virtualization, logs, applications, and services.
In this chapter
- Application MonitoringNetCrunch supports monitoring many applications by Monitoring Packs. It's also easy to create agents for sending data to NetCrunch.
- Managing Monitoring CredentialsStore credentials for monitored systems as reusable profiles, or set them per node. Passwords are kept on the server and are never sent back to a console.
- Operating System MonitoringRead about monitoring Windows, macOS, Linux, BSD, Solaris, and ESXi systems.
- Monitoring Disk Parameters on Unix family systemsRead what disk performance metrics can be monitored on Linux, macOS, BSD, and Solaris.
- Windows Monitoring SetupReading this topic will make your Windows monitoring experience much better.
- Hyper-V MonitoringMonitor summary of hypervisor services and state of virtual machines run by Hyper-V
- WMI SensorsNetCrunch offers a collection of WMI sensors. Basic sensors are designated to serve specific purposes such as monitoring perfmon, process, shares, or time difference. The advanced sensor is more general and allows us to explore WMI classes or create custom WQL queries.
- WBEM SensorsWBEM stands for Web-Based Enterprise Management. It's a set of technologies that describe and share management information about various devices across different platforms. NetCrunch includes three WBEM sensors - Data, Object, and WQL Query: Object that allows access to all available WBEM classes.
- TACACS+ SensorTACACS+ provides access control for routers, network access servers, and networked computing devices via one or more centralized servers. TACACS+ provides separate authentication, authorization, and accounting services.
- Cisco CBQOSNetCrunch's Cisco CBQoS (Class-Based Quality of Service) Sensors offer a sophisticated solution for monitoring Quality of Service statistics through SNMP. This tool is instrumental in analyzing key QoS metrics, providing network administrators with detailed insights to refine QoS policies effectively.
- LDAP MonitoringLDAP Authentication Sensor checks the user authentication process via LDAP that is used by directory services such as MS Active Directory.
- Monitoring Files and FoldersNetCrunch allows monitoring files, folders, and text logs.
- Monitoring Text LogsNetCrunch allows monitoring text file content and has a special sensor for text logs.
- Monitoring Web Pages & DataNetCrunch can monitor requests, pages, and data on the web.
- VMware MonitoringSee how to monitor virtual machines, datastores, hardware status, and the performance counters of host and guest VMs.
- Proxmox VE MonitoringMonitor Proxmox VE clusters, nodes, virtual machines, containers, storage, and Ceph health through the Proxmox REST API.
- Apache Web Server MonitoringMonitor most popular Apache web servers.
- Monitoring Mail ServicesNetCrunch allows monitoring mail content, mailboxes, and checking basic mail server functionalities using a round trip email sensor.
- Sending Data to NetCrunchRead how to send data to NetCrunch and create a custom monitor. You can easily turn any application or script into a NetCrunch agent.
- NetCrunch Self MonitorRead about how NetCrunch monitors itself.
- SQL Query SensorsSQL sensors allow for measuring connectivity, query execution, and result data processing as metrics or statuses. Supported databases: Oracle, SQL Server, PostgreSQL, MySQL, MariaDB, ODBC.
- IP Camera SensorMonitors IP cameras over HTTP/S and ONVIF, capturing snapshots to confirm the camera is working and alerting when the image stops matching its reference.
- iNodes SensorThe sensor monitors usage of iNodes on Linux machines
- Docker Container SensorThe sensor monitors basic statistics of the Docker container
- Monitoring VoIP/SIP ServicesThe sensor checks connectivity and validates the response of SIP service
- DICOM C-Echo SensorThe Sensor checks connectivity and validates response from DICOM capable system
- DICOM Query SensorThe DICOM Query Sensor is designed to monitor the health and performance of a DICOM service. It performs a C-FIND query using configurable search filters (e.g., by patient, study, or other criteria) and verifies that the service responds correctly. The sensor collects key metrics such as response time and total number of results, allowing operators to ensure the DICOM system is functioning and responsive. The sensor is intended for monitoring and alerting, not for detailed query data analysis.
- Scripting SensorsThe Script Sensor in NetCrunch is a dynamic tool designed to execute scripts or programs on the local NetCrunch Server machine and accurately process their results.
- Monitoring Windows Updates and Pending RebootsTrack the state of Windows updates on a machine - installed, available and failed - and find the machines still waiting for a reboot.
- Scheduled Tasks on WindowsA view of every scheduled task on a Windows machine, with its state, next run and triggers. Failed tasks are highlighted, and no extra configuration is needed.
- Palo Alto Firewall SensorPalo Alto Firewall sensor monitors IPSec site-to-site VPN tunnels configured on the Palo Alto device. By default, the sensor alarms when the state of any tunnel becomes non-active. It also allows for the monitoring of specific tunnels.
- NetApp SANtricity SensorThis sensor allows monitoring of the overall health status and performance of NetApp storage using SANtricity REST API.
- HPE 3PAR StoreServ SensorThe sensor allows monitoring of the performance of HPE 3PAR StoreServ storage using Web Services API.
- Veeam Backup and Replication SensorThis sensor allows monitoring of the state of all Veeam jobs and the capacity of backup repositories.
- NetApp ONTAP SensorThis sensor allows monitoring of the health and performance of NetApp storage components using ONTAP REST API.
- Windows Configuration - Hardware, Software, HotfixesThe sensor allows monitoring of the hardware configuration of Windows machines using WMI.
- NAKIVO Backup and Replication SensorThe sensor integrates with NAKIVO Backup & Replication by polling its REST API. It collects repository state, backup storage usage, and job/task statistics to monitor system health and performance.
- Windows DHCP Server SensorMonitors a Windows DHCP Server and its scopes, tracking address pool usage and lease health, and alerting before a scope runs out of addresses.
- Oracle Tablespaces SensorMonitors space in every tablespace of an Oracle database — one instance per tablespace — reporting used, free and maximum extendable size. The percentages are measured against the size the tablespace could grow to, not against its current size.
