Technorati 标签: f5-ltm,performance消失,uptime 497 关于F5-LTM设备的performance图示突然消失(但其他一切正常包括生产业务和相关的snmp监控等)的情况,通过http://tech.f5.com查找相关case,发现为一个已知issue,详见:http://support.f5.com/kb/en-us/solutions/public/7000/000/sol7036.html This is the result of a known issue which exists in the Linux 2.4 kernel used by some versions of BIG-IP. Affected Linux 2.4 kernels compute the system uptime based on the internal jiffies counter, which counts the time since boot in units of 10 milliseconds, or jiffies. The counter is a 32-bit counter, which has a maximum value of 2^32, or 4,294,967,296. When the counter reaches this value (after 497 days, 2 hours, 27 minutes, and 53 seconds, or approximately 16 months), it wraps back around to zero and continues to increment.
F5 Networks Product Development tracked this Linux issue as CR74550, and it was fixed in BIG-IP version 10.1.0 and in Enterprise Manager version 2.0 with implementation of the Linux 2.6 kernel. 在设备上使用bigstart status查看,确实发现刚好超过了497天。 该issue解决方法: 方法一:直接full_box_reboot,这样一般都能解决。 一般方法一就能解决。否则需要执行方法二: 1, Stop the stats daemon by typing the following command:
bigstart stop statsd
2, Create a backup directory for the old files, by typing the following command:
mkdir -p /shared/rrd.backup
3, Copy the existing files to the backup directory, by typing the following command:
cp -rp /shared/rrd.1.* /shared/rrd.backup/
4, Remove the files from /shared/rrd.* directories by typing the following command:
rm -f /shared/rrd.1.*/*
5, Start the stats daemon, by typing the following command:
bigstart start statsd 详见http://support.f5.com/kb/en-us/solutions/public/10000/300/sol10311.html?sr=11008661 方法三:上述方法还未能奏效,则只能进行版本升级了,可以升级到10.1.0以上。
