    with open(file_path, 'r') as f:
        lines = f.readlines()
    return lines[-n:]
result=[]
for key in get_last_lines("/opt/Seeyon/A8/ApacheJetspeed/logs/catalina.out", 500):
    if "Java heap space" in key:
        result.append('Error')
    else:
        result.append('Normal')
if "Error" in result:
    print ("Error")
else:
    print ("Normal")
