Troubleshooting Flatlined Trends in Proficy Historian System

Question:

Are you experiencing issues with your iFix system after losing the original RAID archive storage? Trends initially were blank, but after redirecting to an external hard drive for data collection, they are now displaying as flatlined at a single value. I have tried troubleshooting with the historian administrator, but I seem to have hit a roadblock in resolving this issue. One thing that stands out to me is that the historian server is listed as Machine 3, and the data collector nodes within the proficy historian collectors list are all operational, except for Machine 3, which is showing as paused and in red. Unfortunately, I am unsure of how to proceed from here. If you have any insights or suggestions, I would greatly appreciate your input. Thank you, Ben.

bigLee recently joined iFix and encountered a problem with the RAID archive storage system. Initially, the trends were not showing any data, so they redirected the data collection to an external hard drive. However, the trends are now displaying but remain flatlined at a single value. Despite trying different approaches in the historian administrator, they are stuck and seeking suggestions from others. This issue could possibly be related to the collector not capturing diverse values and getting stuck on the last recorded value. To troubleshoot, one can check the timestamp of the frozen tag in the historian administrator to verify if it reflects the recent time. While this doesn't completely resolve the issue, it narrows down the potential causes. Another noticeable issue is that the historian server is labeled as Machine 3, and the data collector nodes in the proficy historian collectors list are active, except for Machine 3 which is highlighted in red and is in a paused state. Restarting the machine or the collection service might resolve this issue, as it has helped in similar situations before. Feeling stuck on how to proceed further, bigLee is open to any insights or suggestions from the community. It might be a good idea to explore alternatives to GE systems in resolving this recurring issue.

Facing a storage capacity problem, our server, an aging 11-year-old Dell, was on the verge of shutting down due to a full 5MB limit. The server had a degraded C: drive, causing frequent crashes upon restarting. To resolve the issue, we transferred the operating system to a new solid state drive and redirected the archive target to an external hard drive. By doing so, we were able to restore the backed-up archives and successfully bring our services back online. Special thanks to stuccobb and cardosoccea for their assistance throughout the process.

Hi Ben, it sounds like you're dealing with a tricky situation. First off, have you tried running a health check diagnostics on the iFix system? It could be that your RAID archives lost their proper path after relocating storage to an external hard drive. As for Machine 3, it's possible that its paused status is due to an underlying error preventing it from exchanging data properly with the server. I'd recommend forcing a restart of the data collector on Machine 3, and then re-sync the machine with your historian server. You might also want to retrieve and examine the error logs of Machine 3, as it might present more details on what is going wrong. If none of these steps work, perhaps consider reaching out to GE technical support. They’ve been helpful with my iFix issues in the past.

Hi Ben, it seems like you're experiencing a synchronization issue between your historian server and data collector. The red status indicates a possible problem with the connection or the server itself. I’d suggest you to check the network configuration of Machine 3, and confirm if it's able to communicate with the iFix system. Also take a look at the log files which might provide a deeper insight into what exactly is failing. You could also try restarting the data collector node for Machine 3 - sometimes, a simple restart can resolve the problem. Hope this helps!

Hi Ben, it seems like you're experiencing synchronization issues due to the change in storage. Machine 3 is likely the historian server that's having trouble communicating with the new external hard drive. I suggest first ensuring that the drive is correctly formatted for your system. If that's already done, the issue might lie in your RAID configuration. Try unpause the Machine 3 back to operational status and monitor if there are any changes. If that doesn't work, you might have to briefly redirect the data back to another storage source, reestablish the RAID array, and then redirect it back to the new external drive. However, I would advise consulting with a specialist before undertaking anything potentially system-altering.

Frequently Asked Questions (FAQ)

FAQ: 1. Why are the trends in my Proficy Historian system displaying as flatlined at a single value after redirecting data collection to an external hard drive?

Answer: Answer: The flatlined trends issue could be related to the historian server Machine 3 being paused and in red status within the Proficy Historian collectors list. This could indicate a problem with data collection from that specific machine.

FAQ: 2. What could be causing the historian server Machine 3 to show as paused and in red status in the Proficy Historian collectors list?

Answer: Answer: The paused and red status of Machine 3 in the collectors list could be due to an operational issue with that specific data collector node. It might require troubleshooting to determine the exact cause of the problem.

FAQ: 3. How can I resolve the flatlined trends issue in my Proficy Historian system when facing roadblocks in troubleshooting with the historian administrator?

Answer: Answer: If troubleshooting with the historian administrator has hit a roadblock, you may need to investigate further by checking the operational status of all data collector nodes, particularly focusing on resolving the paused and red status of Machine 3. Additionally, seeking assistance from GE Digital support or consulting relevant documentation could also help in resolving the issue.
