If both main and backup proxy are receivable this option allows to spread all requests against RRDtool.
The DNS hostname or IP address of the RRDtool backup proxy server if proxy is running in MSR mode.
TCP port for encrypted communication with the backup proxy.
The fingerprint of the current public RSA key the backup proxy is using. This required to establish a trusted connection.

Removal Method
There are two removal methods. The first, Standard Deviation, will remove any sample that is X number of standard deviations away from the average of samples. The second method, Variance, will remove any sample that is X% more than the Variance average. The Variance method takes into account a certain number of 'outliers'. Those are exceptional samples, like the spike, that need to be excluded from the Variance Average calculation.

Replacement Method
There are three replacement methods. The first method replaces the spike with the average of the data source in question. The second method replaces the spike with a 'NaN'. The last replaces the spike with the last known good value found.
Average
NaN's
Last Known Good
Number of Standard Deviations
Any value that is this many standard deviations above the average will be excluded. A good number will be dependent on the type of data to be operated on. We recommend a number no lower than 5 Standard Deviations.
%d Standard Deviations
Variance Percentage
This value represents the percentage above the adjusted sample average once outliers have been removed from the sample. For example, a Variance Percentage of 100%% on an adjusted average of 50 would remove any sample above the quantity of 100 from the graph.
Variance Number of Outliers
This value represents the number of high and low average samples will be removed from the sample set prior to calculating the Variance Average. If you choose an outlier value of 5, then both the top and bottom 5 averages are removed.
%d High/Low Samples
Max Kills Per RRA
This value represents the maximum number of spikes to remove from a Graph RRA.
