SSH in, chmod +x the install script and then. This allows support staff to use a “graphical” interface to do complex linux/powercli/esxcli things without having to know linux/ESXi. The script will look for all files in the same directory as the GUI script. Copy all files for this job into a directory on ESXi, including GUI script, and run the GUI script. This allows the script to be path agnostic. I have ‘cwd=$(pwd) # Set $cwd to the current directory’ as one of the first lines in the GUI script so I can reference where the script is running from later on. $cwd is a variable containing the working directory of the GUI script. Only root has access.) Copied to global /bin as well to make available for any potential user accounts. Next we cp the above script to root’s bin folder (/usr/sbin/ sbin = Superuser Binary. In troubleshooting i found cp wouldn’t work on it’s own so I had to create the file first. cp command copies current cron file out to touched file. Touch command makes a new file next to the cron file with the filename + date.

This was to address CIM data going stale in our remote monitoring utility (NCentral). If you are deploying VMWare ESXi 6.5 in your environments and need CIM health data, remember to enable it and do not just assume that the WebUI is telling you it is active.Ĭheck out our ESXi Health Monitor for LabTech (Automate) hereĪlso, I’ve addressed this issue by adding a cron job to restart the CIM service everyday at 2AM. We also used esxcli network ip connection list to get a list of ports the ESXi host was listening on to help determine if the port 5989 was active. You can use this list of processes to determine what is running on the ESXi Host. Invoking lsof -nPV | awk | sort -n in the SSH console will produce a list of running processes minus all the junk. Sfcbd-init: Waiting for sfcb to start up. Sfcbd-config: No third party cim providers installed Sfcbd-init: Request to start sfcbd-watchdog, pid 69438 Sfcbd-init: Getting Exclusive access, please wait… You should get an output like the following This process is the TCP Listener that takes CIM requests from probes like ours and returns the health of the hardware. The command esxcli system wbem set –enable true followed by /etc/init.d/sfcbd-watchdog start allowed the sfcb-HTTPS-Daem process to start. A quick /etc/init.d/sfcbd-watchdog start showed us that the service was “Administratively disabled”.Īfter digging around Google for some reference to this new data we came across a blurb about setting an option to allow CIM manager to run. The best way to see what a service doesn’t like is to login to ESXi host using SSH and manually start the process and see what it’s output is. We had set the service to autostart with host so this lead us to believe it must be dying at some point.

We reopen the web UI and looked at the services again and there was our watchdog service stopped. We rebooted the ESXi host and after it came back we tested the connections again and are still failing. By default, this service was turned off, or so we thought! We turned on the service and the UI reported that the service was now running.Įven after several refreshes of the UI it stilled showed running but we still received a connection rejected. The first thing we checked was to see if the sfcbd-watchdog was running, and it was not. We opened the UI and checked the health monitor in the UI and found it was showing “ No sensor data available”. We started following the breadcrumbs which lead us back to the ESXi host.

We were getting connection rejected failures from our probes which resulted in no valuable data being returned. I was recently tasked with an issue where our CIM probe was failing during CIM requests to new VMWare ESXi 6.5 servers we deployed.
