14.1 Target connection issues
Each of the error messages provided by Streamline on a connection failure indicates a different
issue:
Symptom You receive the following error message:
Unable to connect to the gator daemon
at your_target_address. Please verify you have installed the gator daemon on
your target and it is running. Installation instructions can be found in:
.../README_Streamline.txt
Solutions: Make sure the gator daemon is running on your target. Enter the
following command in the shell of your target:
ps -d | grep gatord
If this command returns no results,
gatord
is not active. Start it by navigating to
the directory that contains
gatord
and entering the following command:
sudo ./gatord &
Try connecting to the target again.
If
gatord
is active and you still receive this error message, try disabling any
firewalls on your host machine that might be interfering with communication
between it and the target.
Symptom You receive the following error message:
Unknown host
Solution: Make sure that you have correctly entered the name or IP address of the
target in Address field. If you have entered a name, try an IP address instead.
Symptom You receive the following error message:
Unable to launch. Only one instance
of Streamline may be running on this machine. Please close all instances of
Eclipse and try again.
Solution: Stop any other running Streamline session and try connecting to the
target again. If you cannot find another session, try closing Eclipse for DS-5, then
re-starting it.
Symptom When using event-based sampling, Streamline fails to find the PMU.
Solution:The PMU on your hardware might not be correctly configured to allow
the processor interrupts necessary for for Streamline to use event-based sampling.
Test on alternate hardware or disable event-based sampling in the counter
configuration dialog box.
