我试图使用check_graphite.py插件，但没有成功。
任何人都可以指出我要去哪里错了吗？
xxx@xxx-Aspire-5738:/usr/lib/nagios/plugins$ python check_graphite.py -u (http://127.0.0.1:8080/render/?width=586&height=308&_salt=1349434980.323&from=-10minutes&target=system.loadavg_1min) -w 2.25 -c 2.5 [1] 11103 [2] 11104 [3] 11105 [4] 11106 Status Unknown: Graphite returned an empty list of values -w: command not found [1] Exit 3 .... python check_graphite.py -u (http://127.0.0.1:8080/render/?width=586) [2] Done ..... height=308 [3]- Done ..... _salt=1349434980.323 [4]+ Done ..... from=-10minutes
并因此结束。 有任何想法吗？

而不是用括号括起来，请尝试下面的代码。
python check_graphite.py -u "http://127.0.0.1:8080/render/?width=586&height=308&_salt=1349434980.323&from=-10minutes&target=system.loadavg_1min" -w 2.25 -c 2.5
