First of all, use Cacti s "Rebuild Poller Cache" function under the Utilities menu. If that didn t work ,check if the RRD file is actually updating with new data. To do this use the command:

rrdtool last [filename.rrd] This will output the last time (in unix timestamp) that a new value has been inserted into the RRA file which you can compare to the current time that date +%s will output.

If it s not updating with data then you should change the cacti log level to DEBUG via the settings page on Cacti s web UI and look for appropriate messages. If the poller couldn t get the data then it s usually an issue relating to connectiviy/SNMP. You can further check issues as such by manually polling the specific OID on that host:

snmpwalk -c[SNMP COMMUNITY] -v2c [HOSTNAME OR IP ADDRESS] 1.3.6.1.2.1

You can use the above command and OID (1.3.6.1.2.1) just to see if you re getting a reply. If that worked then you should change the command from snmpwalk to snmpget and the OID to the actual OID you re trying to poll and retry.

如果复兴共和与民主运动正在更新新的数据,但你仍在把NaN重新列入你的图表,那么我建议对数据来源(通过数据模板)与你的投票间和投票人之间的间隔有关的心灵和步值进行研究。

These values determine how many times the RRD file will miss data before inserting a NaN. The cronjob calls the cacti poller to start performing it s polling cycle. The poller interval is the actual time that the poller will wait between two polling cycles if it was indeed invoked in time by the cronjob.

So for 1 minute polling (on the poller and the cronjob) you will have to use a step of 60 (seconds) and a heartbeat of 120. For 5 minutes polling, the step will be 300 and the heartbeat will be 600.

这主要是因为有人在环境页上改变了投票人之间的间隔。

你们是否确信你收集了足够的数据?

如果贵国的复兴共和与民主军有1分钟的分步,而贵国的第一份区域局有1个综合数字(1cdp=1pdp),那么,在您期望看到图表中的任何数据之前,你应至少收集X分级(+1)的数据。 确保你收集的数据至少与步骤规模一样多。

如果你收集10个雷区的数据,而没有显示任何数据,那么就能够确保你实际收集数据,确保你得到的数值在幅度之内,并且正在使用。 查阅复兴共和与民主军档案的最后修改时间。 印制你更新的价值观,以核实这些价值是你认为的。

你们应当把Cacti的地块增加一倍。 我移走了图表过滤器中的数值,在图表中发现了一小部分数据,因此,你只得加以调整。
