Chances are that if you are an avid Windows user, you have probably come across the Perfmon utility at least once in your exploration of system and network monitoring. Most of LogicMonitor’s Windows data collection uses WMI queries, but we do utilize Perfmon counters for our Windows SQL Server, Exchange (earlier versions), and SMTP DataSources. If you see … Continued
To monitor a Citrix XenServer installation, the LogicMonitor collector needs credentials to connect to the XenServer(s). Define the properties xen.user, xen.pass, and xen.url on either the global, group, or device level. Please note: unless you are using Active Directory authentication, the xen.user will typically be root. Add the XenServer as a device, as normal. Note: … Continued
Solaris 10 should have Net-SNMP package installed already. It’s preferable to use it instead of the Sun’s SNMP package. Below info is taken from this documentation. Please note that some Solaris DataSources require SSH credentials. Please refer to the DataSource description to verify whether these are required. Log To disable Sun’s SNMP #svcadm disable svc:/application/management/snmpdx:default … Continued
FreeBSD requires activating the snmp daemon, and configuring to report more information than it does in the default setup. We also recommend ensuring ntp is enabled and configured. Enabling SNMP FreeBSD ships by default with the bsnmpd daemon. This is not started by default, and is configured by /etc/snmpd.config, with a default community of ‘public’. … Continued
Overview LogicMonitor’s Windows Server Failover Cluster (WSFC) monitoring is performed on a virtual device called a virtual network name (VNN). Each VNN is assigned a virtual IP address and, in some cases, multiple virtual IP addresses for specific services. There is no physical device for the cluster; nodes are added as physical devices or virtual … Continued
Configuring Windows Firewall to Allow Remote WMI When obtaining data from a remote computer, WMI must establish a DCOM connection. If a Windows firewall is running with default settings, it will not allow this connection. To allow remote WMI through the firewall, on the computer to be monitored, perform one of the sets of steps … Continued
Overview LogicMonitor uses SNMP to monitor host filesystem capacity across a variety of operating systems. Filesystem Monitoring DataSources LogicMonitor offers several DataSources for filesystem monitoring via SNMP: Understanding the SNMP_Filesystem_* DataSources The SNMP_Filesystem_Usage and SNMP_Filesystem_Status DataSources offer filesystem usage and status monitoring respectively for operating systems such as Linux and Unix. These two DataSources were … Continued
In order to get detailed performance monitoring of physical disk drives, LogicMonitor requires a specific configuration in the net-snmp snmpd agent. Add this line: extend diskstats /bin/cat /proc/diskstats to snmpd.conf, and restart the snmpd daemon. The DataSource “Linux Disk Performance-” will then discover all physical drives and monitor their performance. (You can manually trigger ActiveDiscovery … Continued
To monitor a Linux NFS server, an extension to the snmpd.conf is required Add this line: extend lm-nfsd /bin/cat /proc/net/rpc/nfsd to snmpd.conf, and restart the snmpd daemon. The Linux NFS Server stats- datasource will then discover and monitor the performance of the NFS server. (You can manually trigger ActiveDiscovery to speed up that process.) NFS … Continued
Due to our collector architecture, our script collector method can only launch scripts from the local collector machine. The collector is not natively able to directly launch files or execute scripts that are present on aremote host. Generally, it is best practice to avoid remote execution for monitoring purposes, whenever possible. In most cases, it should … Continued
