Cacti update rrdtool

These are settings to place RRDfile updates into a database table and cache them. Then, on a periodic basis dump those updates to disk at once. You can see the available settings in the image below. If you disable it, the poller must first clear the cache before it can be fully disabled.

So, disabling is not immediate after it has been activated for some time. Cacti will spawn the number of collectors specified by this setting. Maximum Records - This is a threshold in cache records that if that number is exceeded, the cache will immediately begin to be cleared. This setting works together with the How Often setting. Maximum Data Sources Items Per Pass - Cacti will count the number of distinct data sources in your system, and then divide it by this amount, and then make X number of passes through the data.

Developed in the early s by Ian Berry as a high school project, it has been used by thousands of companies and enthusiasts to monitor and manage their Enterprise Networks and Data Centers. PHP Must also be compiled as a standalone cgi or cli binary.

This is required for data gathering via cron. We mark the php-snmp module as optional. So long as you are not using ipv6 devices, or using snmpv3 engine IDs or contexts, then using php-snmp should be safe. Otherwise, you should consider uninstalling the php-snmp module as it will create problems.

We are aware of the problem with php-snmp and looking to get involved in the php project to resolve these issues. RRDtool is available in multiple versions and a majority of them are supported by Cacti.

Data sources utilize input methods to gather data from devices, hosts, databases, scripts, etc The possibilities are endless as to the nature of the data you are able to collect.

Graphs, the heart and soul of Cacti, are created by RRDtool using the defined data sources definition. To do this, edit a graph that has the issue, select Turn On Graph Debug and a new section should appear beneath the graph. This should show both the command and what output we received from the tool. If the output above isn't helpful, simply copy the command section and then run it as the user which the website runs as.

For Windows, the following command will allow you to spawn a command prompt as the website user, from which you can then run the above command to see the output. The newly created command prompt should show the user name if you have entered the correct password. What is Spine? Support Cacti Report an Issue. Release 1.
