There are two main scenarios for using the agentcmd utility:
With an agent on a system that has been added to Uptime Infrastructure Monitor. In this case, the hostname is in the up.time DataStore.
With an agent that has been deployed on a system that has not been added to Uptime Infrastructure Monitor. If there is no agent on the system, or there are network problems, agentcmd returns the following error message:
ERR Unable to contact Agent (10.1.2.34 on port 9998)
You can use agentcmd in two ways:
Using agentcmd at the command line Using agentcmd in an agent-side script
Using agentcmd at the command line
The command line syntax of agentcmd is:
agentcmd <t#> <-/+s> <-p #> hostname command
Where:
t# = use timeout.
-s = do not use an SSL connection to the agent (default).
+s = connect to the agent using SSL.
If SSL is not enabled on the host, the following error message appears:
ERR The host was not configured to use SSL
-p # = connect to the agent on the specified port (default is 9998).
hostname = the name or IP address of the host on which the agent is running.
command = the agent command to run.
For example, to get basic system information from an agent running on the server Solaris1, type the following command:
agentcmd +s Solaris1 sysinfo
The agent will return output similar to the following:
SYSNAME=Solaris1 DOMAIN=myDomain.com
ARCH="SunOS Solaris1 5.9 Generic_118558-03 sun4u sparc SUNW,Ultra-Enterprise" OSVER=5.9

Using agentcmd in an agent-side script
As with netcat, agentcmd is typically used in a script on the monitoring station to perform the following tasks: Unable to render embedded object: File (worddav0e23da46291fd27cf7d38d55e66cea8d.png) not found. Contact an agent system.
Unable to render embedded object: File (worddava138aea4622cb8d4b565b823c19c0a1d.png) not found. Attempt to run a predefined agent-side script. Unable to render embedded object: File (worddava138aea4622cb8d4b565b823c19c0a1d.png) not found. Return the results of an agent-side script.

The following example illustrates how to run agentcmd in an agent side script:
