You are on the right track. Once you have a list, you save it for the next pass, say a minute later, and then if they change too much between passes, you could alert. For instance, at one minute intervals, 50% of one CPU would be 30 seconds. You might want to have an alerts sent file, or empty flag file in a flag dir, to reduce alerts every minute from the same problem proc to once per clock hour or so. You might want to send one updated list of all problem procs, not an alert per. Maybe make the list of all every minute (without time stamps and headers), and if it is the either different (comm -3 file1 file2 or just cmp) from a minute ago or both the first minute of the hour and not empty, then email it out (with time stamp and header, host name first in subject so testing and prod are not confused).

GIT-CHECK-ATTR(1)                                                   Git Manual                                                   GIT-CHECK-ATTR(1)

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname... git check-attr --stdin [-z] [-a | --all | attr...] DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
-a, --all List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be included in the output. --cached Consider .gitattributes in the index only, ignoring the working tree. --stdin Read pathnames from the standard input, one per line, instead of from the command-line. -z The output format is modified to be machine-parseable. If --stdin is also given, input paths are separated with a NUL character instead of a linefeed character. -- Interpret all preceding arguments as attributes and all following arguments as path names. If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF unless -z is in effect, in which case NUL is used as delimiter: <path> NUL <attribute> NUL <info> NUL <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either: unspecified when the attribute is not defined for the path. unset when the attribute is defined as false. set when the attribute is defined as true. <value> when a value has been assigned to the attribute. Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by overfilling an input buffer or reading from an empty output buffer. EXAMPLES
In the examples, the following .gitattributes file is used: *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified o Listing a single attribute: $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java o Listing multiple attributes for a file: $ git check-attr crlf diff myAttr -- org/example/MyClass.java org/example/MyClass.java: crlf: unset org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing all attributes for a file: $ git check-attr --all -- org/example/MyClass.java org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing an attribute for multiple files: $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified o Not all values are equally unambiguous: $ git check-attr caveat README README: caveat: unspecified SEE ALSO
