We are trying to figure out the best method to update our environment activegates that are set up to run private synthetics. In the documentation around updating activegates, it says you can just install the new version over the old one, but when we do that with the '--enable-synthetic' and '--enable-browser-monitors' options, we get the error below:
ERROR: Parameters --install-modules, --enable-synthetic, --enable-browser-monitors and --enable-zremote are not valid for an update and are mutually exclusive, with the exception of --enable-synthetic and --enable-browser-monitors, which can be specified together. To proceed, perform the following actions as user 'root': first uninstall Dynatrace ActiveGate and then perform an installation, specifying appropriate parameter(s), depending on your requirement, e.g.:
My question is are we going to have to uninstall and reinstall on these particular activegates every time a new version is available, or is there a method to updating these without completely uninstalling/reinstalling?
Look here, synthetic is only property in config file, so upgrading without extra arguments should work for you.
I just ran the install in my test environment without any parameters and it basically changed the activegate into one used for routing traffic and monitoring cloud environments, so now my synthetics are dead.
So for a synthetics enabled activegate, what should the upgrade process be? What would I need to add into the custom.properties file? I'd like to get this process down, as we have a few of these to update, and manually uninstalling and reinstalling every time a new version is available really isn't feasible.
You can just run the install on the gateway without any perimeters and it will retain current settings and just update the version. I've done this without error on my internal, external and custom metrics/Plugins Activegates without any problems, WE typically do a snapshot of the host that is being upgraded just before in the event that something does go sour we can just jump right back. Never had to uninstall and install to be on the latest version.
Hey Ryan, Yes We have done this for CMC activegates that handle oneagent traffic, Mobile app alerts, internal synthetics, external synthetics, and custom plugins. I have attached a screen shot with the settings we use when we download the linux install/updated version.
You could select that second radio button and it will pass the perams for synthetics but i dont believe thats needed since synthetics are already running - the install file just updates
Everything we have tried has worked as expected in regards to upgrades, except for the second option in your screenshot. When we run the install with the parameters it mentions, the install fails telling us that parameters are not needed. Then when we run it with no parameters, it blows away synthetics and turns the activegate into the first option (route traffic, monitor cloud environments). I am going to try it with the option Yos mentioned above with the modification to the custom.properties file, and I'll report back.
