You might have a look in the
sar output if your system uses
sar - which may or may not be the case.
Otherwise, you might have some performance monitoring tool running and might find information in its output.
Otherwise, i suppose you are out of luck: you can see the
current swapping - quite detailedly so - in the
vmstat output, but the figures from yesterday are not there (and to my knowledge anywhere saved). In this case you might set up something - log
vmstat to a file, start
sar, etc.. - and wait until the problem occurs again.
I hope this helps.

git-check-attr
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...] < <list-of-paths>
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 file names from stdin 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
