-------------------------------------------------------------------------
from the failed dtest - largecolumn_test.TestLargeColumn, the test logic
depends on format of gcstats output:
{code}
def directbytes(self, node):
def is_number(s):
try:
float(s)
return True
except ValueError:
return False
output, err, _ = node.nodetool("gcstats")
logger.debug(output)
output = output.split("\n")
assert re.search('Interval', output[0].strip())
fields = output[1].split()
assert len(fields) >= 6, "Expected output from nodetool gcstats has at
least six fields. However >= fields is: {}".format(fields)
for field in fields:
assert is_number(field.strip()) or field == 'NaN', "Expected
numeric from fields from nodetool gcstats. However, field.strip() is:
{}".format(field.strip())
return fields[6]
{code}
