It’s been a while since I checked
uptime on few servers that I manage at work. And by “a while” I mean “a while“. Here are five records for you to be impressed.
- ldap-master – this server has a pretty easy life. It is a master node of our internal LDAP cluster. All it has to do is answer the queries of about 20 other servers and a couple of web applications.
[leonid@ldap-master leonid]$ uptime 2:39pm up 462 days, 9:19, 3 users, load average: 0.00, 0.00, 0.00
- news – this server is under bigger load constantly. It runs as a slave of our internal LDAP cluster. It hosts one of the havier used web applications with database backend. It also runs a news-mail-news gateway, which allows employees to read and post to several heavy mailing lists via a single subscription.
[leonid@news leonid]$ uptime 2:40pm up 455 days, 10:59, 1 user, load average: 0.11, 0.03, 0.01
- devzone – this is our main development server. About 20 people are constantly using it. It also hosts one of our RT ticketing systems, as well as a few other web applications. There are also a few processes running in test mode.
[leonid@devzone leonid]$ uptime 2:44pm up 404 days, 13:12, 11 users, load average: 0.07, 0.06, 0.00
- gorilla – our main file server. It hosts homes for more than a hundred users. It also has a bunch of file areas accessible via FTP, NFS, and Windows file sharing (SMB). It also hosts mirrors some mirrors of apt repositories and even Tucows. Some of it is also used for network backups.
[leonid@gorilla leonid]$ uptime 2:46pm up 394 days, 10:36, 2 users, load average: 0.00, 0.01, 0.15
- backupsrv – this is our backup server. It is one of the most heavier used servers on our whole network. It is responsible for backup and restore of about a hundred hosts and devices. Most of these are done on the daily basis. This server gets most of its reboots from the SCSI equipment errors.
[leonid@backupsrv leonid]$ uptime 2:51pm up 284 days, 6:55, 2 users, load average: 0.00, 0.00, 0.00
uptime on several other hosts and all of them are either approaching one year, or passed it already. All of these hosts are running some version of Red Hat distribution. Versions vary from Red Hat Linux 6.2, through Fedora Linux Core 3, to Red Hat Enterprise Linux ES 4.
