Can globally-defined arrays be accessed? Because if so, I can't figure
out how and I can't find any reference to this in the documentation.
Here's an example:
body common control {
bundlesequence => { "test" };
}
### Read in lines of the form KEY="VALUE" from the
### cache file into the global array "asset_cache"
bundle common g {
vars:
"asset_cache_file" string => "/var/tmp/.asset_data_cache.cf3";
"num_asset_cache_entries" int => readstringarray(
"asset_cache", "$(asset_cache_file)", "#[^\n]*", "=", 30,
3000
), comment => "Number of entries read in from asset cache
file.";
}
### Print out the contents of the global array
bundle agent test {
vars:
"at_fields" slist => getindices("$(g.asset_cache)"); ###### THIS
DOES NOT WORK
reports:
linux::
"Read $(g.num_asset_cache_entries) entries from
$(g.asset_cache_file)";
"Asset cache value: $(at_fields) =
$(g.asset_cache[$(at_fields)][1])";
}
This results in the following output:
R: Read 19 entries from /var/tmp/.asset_data_cache.cf3
R: Asset cache value: $(at_fields) = $(g.asset_cache[$(at_fields)][1])
I know you can't iterate over global LISTS and have to make local copies
to access their contents. So how, if possible, do you access global
arrays?
Thanks,
Justin
