@Fernando-Gietz said in Use an external database:

My FOG version is 1.5.5 for working branch, the last version.

So you don’t have the fixes I pushed to dev-branch. We might consider merging your code changes form working to dev-branch soon. This way you can make use of all those changes.

@Tom-Elliott What do you think?

@Fernando-Gietz said in Performance Monitoring tools:

We use Nagios to monitoring the server status but not use any plugin to see the activity of MySQL or Apache. Do you use any plugin to monitoring these services?

We use plugins for both mysql and apache monitoring. But I feel I must make a distinction between performance monitoring and service level monitoring. We do service level monitoring, in that we only check if the service is functional (what ever that means like mysql connections, or basic http queries) as well as critical service parameters. We dont monitor things like inbound network traffic for sql server, because its really not important to know how well the sql server is functioning (I know you can make an argument either way). As you know nagios is just a go/no-go monitoring system. If you couple that with mrtg or such then you can get trending over time. That is why we really like Centreon because it has nagios coupled with a few other opensource softwares in one package. You can get that trending over time of the actual recorded value as well as the go/no-go status.

Performance monitoring is collecting a large amount of metrics to understand how the system as a whole is functioning, not just the critical bits. You could use performance monitoring environment for forensic investigations over time to understand how metrics have changed. You may be not so interested in the individual services here.

So when looking for a monitoring tool, you need to decide what is important about that device/service. Why does it exist? What function does it perform? What would happen if that service disappeared? That is how you should decide what to monitor regardless of the tool.

For example: Lets say you wanted to monitor your FOG server for both availability and performance metrics. What do we know about your FOG service? Well it runs on linux, it uses a tftp server, apache server, a ftp server, and nfs.

So for linux what is important?

Is it reachable on the network? How utilized is the CPU? How much free memory is there? How much free disk space is there on the /images disk? Are the tftp, http, ftp services running in memory? (notice I didn’t mention if they were working only if they are running in memory)

For the tftp server what is important

Is it listening on port 69? Does it respond to a file size request?

For the http server what is important?

Is it listening on port 80 Does it respond to http requests? If your site uses php does it respond properly to a php page call? What is the percentage of CPU does the apache service use?

And so on for monitoring. The point is to understand what you want to inspect before you pick the tool. Then find the tool that fits your budget and time you are willing to invest in setting it up.

At my brothers company they use a product called WhatsUp Gold and they loved it before they moved to PRTG which they now love more. But they had the budget but not much time to build it themselves. In my case I’ve been running nagios monitoring servers on and off since 2000. I don’t have a problem spending time to build new installs.

@ragnurenson so, I’ve just tested after applying the commited changes and everything works fine! Thank you for pointing out the github commit and thanks @Fernando-Gietz for the awesome work!

If I can make a suggestion, I’d say it would be nice to have that search filter implemented in “List All Hosts” screen on Active Tasks!

I made the changes and did a test run, dev-branch completely passed.

Unless, of course, you’re trying to make it core usable? But the only time this would be viable would be if LDAP plugin is in use. Of course other plugins may want to make adjustments here as well. I need to think on this a little bit.

Thanks to Wayne I had access to the RHEL 7 machine for a quick test and seems like we hit it with the latest fix. Installer went through like a charm. So RHEL is back in the race I suppose.

@Sebastian-Roth Thanks for you answer, i’ll try next time.

Sincerely.

Jérôme

@Doctrg You should be able to go straight from 1.3.5 to 1.5.4 I think. Make a full DB dump on the old server, install mysql on the new one by hand (yum install mysql mysql-server), import DB dump and then start the FOG 1.5.4 installer. When it asks you to open the web interface go ahead and it should upgrade your database structure - usually does without an issue.

Not saying there can’t be anything going wrong but mostly this is going fine. As you still have the old server (or at least a full backup of machine and DB), you can always give it a try. Shouldn’t hurt.

@tom-elliott we do all the installing manually… Could you please elaborate the steps…

Like @Tom-Elliott said, the initial postdownload script always runs. However, you can use CASE or IF statements to either call a function or open another script. Here is my current postdownload script that I got from one of @george1421 and his wonderful driver injection scripts found here

#!/bin/bash . /usr/share/fog/lib/funcs.sh [[ -z $postdownpath ]] && postdownpath="/images/postdownloadscripts/" if [ $img == "Win7BaseVM" ] || [ $img == "Win10BaseVM" ] ; then case $osid in 5|6|7|9) clear [[ ! -d /ntfs ]] && mkdir -p /ntfs getHardDisk if [[ -z $hd ]]; then handleError "Could not find hdd to use" fi getPartitions $hd for part in $parts; do umount /ntfs >/dev/null 2>&1 fsTypeSetting "$part" case $fstype in ntfs) dots "Testing partition $part" ntfs-3g -o force,rw $part /ntfs ntfsstatus="$?" if [[ ! $ntfsstatus -eq 0 ]]; then echo "Skipped" continue fi if [[ ! -d /ntfs/windows && ! -d /ntfs/Windows && ! -d /ntfs/WINDOWS ]]; then echo "Not found" umount /ntf >/dev/null 2>&1 continue fi echo "Success" break ;; *) echo " * Partition $part not NTFS filesystem" ;; esac done if [[ ! $ntfsstatus -eq 0 ]]; then echo "Failed" debugPause handleError "Failed to mount $part ($0)\n Args: $*" fi echo "Done" debugPause . ${postdownpath}fog.deletelog . ${postdownpath}fog.drivers #. ${postdownpath}fog.ad umount /ntfs ;; *) echo "Non-Windows Deployment" debugPause return ;; esac fi

You can see that I have an if statement at the beginning to only run his driver injection script if the image name is one of my golden image VM’s.

Removed. Well, kept the surface-pro-4 matching element, but just removed the 7156 portion.

@maikbat by default the api access is disabled. Check fog configuration ->fog settings->API Settings and enable

@tom-elliott thank you so much! You are a rockstar. I look forward to 1.6!

Thank you 🙂 That worked great!

@tom-elliott How can i request to /fog/host/search/xx:xx:xx:xx:xx:xx ?
I will have an error with this for illegal url chars can i send it with data ?

And

http://domain.com/fog/host/search/randomhostname

return a white page (403 Forbidden error to get the search route)

Solved. Because Fog’s apache settings are configured in a vhost, the logs are going here on Debian 9:
/var/log/apache2/other_vhosts_access.log

@andyb2000 said in Plugin hook deploy problem:

function groupDeployPost($arguments)

I guess you need to give us more context. Hooks are usually

getClass is defined in class FOGBase (ref) which is inherited by EventManager, which is inherited by Event, which is inherited by Hook. So if you do class myOwnDeployPostHook extends Hook you should be able to use self::getClass(...

@DarkStorm007 what specifically do you want to change about the form? Is it that its showing in english and not the system language? We do have Spanish-Spain (es-Es) translations, but not for Mexico (es-mx). If you’d like to add a translation, see this thread: https://forums.fogproject.org/topic/9068/help-wanted-client-internationalization and I can include it in the next build/release.
