I am aggregating using the stack function as the index: @s[stack()] = count();
This works great. However, I found that in addition to how many times each stack appears, it would also be useful to know which stacks were called shortly before the script exited. So I thought to make an associative array with the same indexes, and store the timestamp the last time they were set: ts[stack()] = timestamp; This gives me an error: tracing function stack( ) may not be called from a D expression (D program context required) Why can't I use stack as the index to an associative array when I can use it as the index to an aggregation? Am I doing something wrong? And if I can't use it, does anyone have a suggestion how to store the time of the last call of each stack? -- blu It's bad civic hygiene to build technologies that could someday be used to facilitate a police state. - Bruce Schneier -----------------------------------------------------------------------| Brian Utterback - Solaris RPE, Oracle Corporation.
