Best Cracked 1.8.9 Servers
Annemie
Hi, our master and media servers are all NBU 7.1 on Windows 2008 R2. We have 10+ file servers (all are Windows 2003, NBU 7.1 client). We found the data sizes in these file servers grow very fast. Now the total sizes grow to 10+ TBs. Every time it takes very long time to complete the full backups of these file servers. My question is: is there any way to improve the backup performance? what are best practice to back up file servers? One possible way may be to consolidate the file servers to fewer number of servers and then convert them to SAN media servers. Any other suggestions/recommendations? Thanks in advance.
My question is: Should I point ALL of my networking equipment to the same 3 NTP servers? Or should I pick different public NTP servers for the Virginia and California offices due to distance from the NTP servers I chose for the Illinois group?
This is why you use three NTP Servers. The NTP protocol is very clever and it can drop a server that has invalid time. It also works latency into the calculation so that the time your device receives is accurate normally to within
So we have branch offices that utilize a VPN tunnel back to our main office. Since technically they are on our same network, should I point everything to one internal device at our main office? And then have that internal device at our main office, that all of the others are pointing to, point to three of the NTP pools?
I think that depends on your tunnel speeds. I would be tempted not to add any extra traffic if I could help it. That being said I would point your branch routers to ntp.org and other internal branch devices to your branch router. Just my 2 cents.
I prefer to keep time aligned with Active Directory (if there is one in use) so that any possbile external AD authentication works for sure (example vcenter appliance). Kerberos doesnt like time skew. So Domain Controller running PDC role gets time with NTP and acts as a NTP server.
I'd like to know if there are any documentation or best practices that the community would like to share here. I want to know how to better manage and improve our Server experience for our end users.
Also this more pertains to the folks at Inductive Automation, In kepserver if you are using the OPC quick client and you watch the status. Even though in the status window of the OPC server you can see when a device becomes unavailable, sometime it takes time before the status goes from GOOD to BAD. Which item is FSQL watching? Is it the flag that comes up and says Device not repsonding or is it the status which would similarly be used in the Quick CLient?
What exactly is considered a process? I ask because it also said that each subscribed groups constitutes 2 or 3 threads. But it only vaguely mentions tags, so does more tags in a group mean it takes more threads and more processes?
It said depending on how the client connects upto the server that the actual amount of available groups could be 900 if it uses 2 threads or 600 if it uses 3 threads. So is a group considered each individual tag or if you have a folder in Kepserver that has 20 tags in it that would consititute one group.
Eric, thanks for all the informative replies. The reason I ask such questions is actually multi part. One part is for the knowledge being as I have no real formal training on this type of application. Another part is due to understanding design considerations. And the big part right now is due to a problem that recently arose and I am hoping to be able to recreate. The problem dealt with ASCII string that I have in the data stream. In my project that I am designing, with a lot of great assistance from the team at IA and some of the really smart people on this forum, I have a group of historical items which is recorded to an SQL table. In this is the said ASCII strings. On a recent run, before our server went south and had to be reinstalled, while running all 9 connected machines, one machine the ASCII string would not update. All the other data was being updated but for some reason not any of the ASCII. This is the second time that this has happened. And it does not follow any specific pattern. The last time it was the machine we refer to as #52, the most recent time it was machine #2. However both times before I was able to get into the actual server where the software is installed something happened that shut down all processes. In the first case it was the log file in SQL and in the second the witness program detected a problem of some sort and caused the IT dept to conceed that the server needed rebooted. When they did it crapped out. So neither time was I able to get on the server and run any of the diagnostics to find out what could be causing the problem. I want to know that as this system grows and becomes fully implimented that this is not going to be a major problem that comes back and bites me in the behind. Ole man Murphy and I are great friends. So I guess another reason for all these questions is for some C.Y.A. I just want to know that I making the best choices possible.
Graybox OPC Server Toolkit lets the programmer to create robust and highly effective OPC Servers within the shortest possible time. This toolkit eliminates the necessity of implementing all of the numerous OPC interfaces and COM programming. Graybox OPC Server Toolkit supports OPC Common 1.00, OPC Data Access 1.00, OPC Data Access 2.05a, OPC Data Access 3.00 (not available in Graybox OPC Server Toolkit 2.x versions). Graybox OPC Server Toolkit is fully compatible with Windows NT4/2000/XP/2003. Windows 95/98/Me operating systems are not longer supported (starting from version 2.0).
Eric - I have no problem with you pushing your OPC Server here. Our software should work well with whatever OPC package. In my experience, Matrikon and Kepware both work really well. I love to hear about features and implementation details that distinguish your product. I have experienced performance hits and browsing issues with RSLinx on large systems.
Hello everyone.
I just started my journey in Conan Exiles 2/3 days ago, I have been playing solo on the single player mode and i really enjoy it.
If i wish to play on a online server, PvE only, are there any servers out there worth considering where people play under vanilla rules?
Like I said, there are rules, but quite often rule breaking is only dealt by admin if other players report them, so with that said, I can highly recommend reading the rules to avoid a possible wipe and ban(most people likely never do)
Difficult to find one that is exactly like officials. The majority on PC are modded. The game is quite old already and not many are into hosting a server to play vanilla. Stay in sp or try officials until you get the basics at least. If you go for an official, I would go for one with low population in the hopes for better performance.
These were some of the official server I have had an experience with, maybe others have something to add.
Also be aware that servers and population can change over time, some of those I mentioned may now be different from how I experienced them back then
Rules are designed to be very interpretable. And there is a lot of abuse going on on officials. Especially if you are new to the game, there is a lot that you can do wrong that can get you banned very easily.
Some of my experience on metrics, windows endpoints with a tuned sysmon config, audit policy and wef generate about 2mb of logs per day each, with an ad infrastructure, exchange etc this on average for all the devices ends up near 7mb per device. More tuning could be had.
Taking windows logs from over 800 devices gives me over 300 eps. I have alot of config files in logstash for parsing and tuning, it has 8 cores and 8 gb ram with 6 for JVM. CPU utilization only goes above a few % when i change a config and logs burst in when it comes back. RAM/JVM could be reduced as its not using anywhere near that.
Hopefully this gives you a starting point but be prepaired to need to turn things up unless you have the kit to chuck alot of resources at. Remember the max JVM is 31/32gb and for ES recommended that this is 50% of RAM
i gave an example of my logstash spec, 8gb, 6gb of which is jvm and 8 cores. Realistly that is overkill but i have the resources. Disk wise for logstash it can be small. I use about 100gb but again overkill.
As for the ES servers, it boils down to your retention and use case. There are guides on shard sizing, this is a little out of date, the ratios have gotten better - How many shards should I have in my Elasticsearch cluster? Elastic Blog
That should do you well, tuning the events coming in will make a big difference to eps and retention.
Although Kibana does not need that much RAM, the logstash could get away with half that easy as well. Would be better to have 2 logstash servers of 8gb each.
Elastic:
Little overkill for 100 servers on the elastic side but will do very well. I have 500+ devices on 3 nodes with each 32GB ram each and have no starvation issues. The disk backend will kill you faster then then memory. At 500Gb you will be VERY surprised how fast that will disappear. As always in storage never exceed 80% utilization. Running winlogbet alone will take all of that in about 3 week if you don't trim out unneeded events for your use case. Use LVM and try and split the volume over several VMDK's/QCOW volumes. If it's physical it has to be SSD and 1 won't survive long "killed a few in dev already". Storage will be your pain point.
You're spot on! In addition, depending on the configuration you could also look into using IntelliSnap or NAS. Adding the File Server as a NAS () _nas_file_servers.html allows you to specify multiple access nodes / proxies to divide the load across multiple systems. You will have to take into account that adding more resources normally also means a higher impact on the storage offering of the VM and/or the underlying storage, so make sure you keep an eye on this.
